Hello,do you know which material in the library should be used for METGLAS Alloy 2605SA1?Thank you.
I’m sorry but I don’t know. I believe you can define your own materials though from the underlying magnetic properties. Good luck!
@@ElectronicmindsUK I am just wondering why it is not included in the Library,i thought it is allready a common material.Thanks for the fast answer.
The power requirement to gate drive high power mosfet can reach 2W as you described using the total gate charge and the switching frequency. I came across the same family of isolated dcdc chips for gate driving murata. My question is, the brief peak current the Mosfet requires is sometimes as high as 2A if high switching frequency is to be achieved, will these murata chip be able to supply that?
Yes, the peak current during the gate drive transitions comes largely from the ceramic decoupling capacitance we use both on the dcdc output and local to the gate driver IC. The isolated dcdc really just responds to the average current since the peaks are so short.
I enjoy this webinar. it is extremely useful from engineering view point. Can you do another webinar on actual high power for example 2-3KW output convertor
Thanks for your feedback and good to hear that this was useful for you. We are working on a different set of videos now but will put your request onto our list for future ideas. Many thanks!
Excellent!Good job.
Excellent Jose. 👍
Thanks for your sharing. In the presentation, talking about the potential parasitic turn-on issue for the low side mosfet. Is it the same potential issue for high side mosfet in half bridge configuration? Thank you.
Thanks for your question and apologies for the delay in replying. Yes, the miller effect can induce parasitic turn on in both the low side and high side devices. The mechanism is the same. I hope you enjoy the rest of the content here.
Hello can I get a copy of your white paper just for my study purpose
Sure, please let me know your email and I will send you a copy.
Ah yes, the Traxxas E-maxx...brings back memories! Looking forward to this.
Well spotted! It is a great platform for experiments.
Totem Pole PFC: if you turn on a mosfet it also shorts the body diode. the mosfet shorts in both directions, so there is no current in the body diode. in high curent recitifiers mosfets are acterly used as rectifiers when they are turn on there is 0V over the body diode.
Hey guys thanks for this series it’s excellent! Would love to see more videos on gate drive design with emphasis on the different protection mechanisms that can be implemented. Again, thank you!
Thanks for your great feedback. What sort of gate drive protection mechanisms are you interested in most?
@@ElectronicmindsUK hey guys sorry for the late reply To be honest if you could do the following that would mean the world to me 1. Overcurrent Protection (OCP) 2. Short-Circuit Protection (SCP) 3. Under-Voltage Lockout (UVLO) 4. Over-Voltage Protection (OVP) 5. Thermal Protection 6. Desaturation Protection (DESAT) 7. Dead-Time Protection 8. Phase Loss Protection 9. Reverse Voltage Protection I know that’s allot of material so that being said 123456 are by far the most important. Worked schematic examples of each would also be amazing
Hey guys, Just wanted to check in to see if this is something that you would still be interested in doing a video on. I understand there were allot of protection systems listed. I think an episode that focuses on the major protection mechanisms used in industry with some accompanying circuit simulation would be awesome. There’s not that much gate drive protection videos online and the few that are are pretty poor in my opinion. Thanks for the excellent series, it’s really helped me gain knowledge in power electronics Doron
Grateful for what have you done. I have a small doubt though, how did you measure AC resistance i.e. @100kHz could help me figuring this out. I have designed a component but I wanted to it validate with my simulation results. So could you help me how to measure AC resistance. I have impedance analyzer with me but the real part of the impedance measured is giving effective resistance but not the winding resistance alone.............Thanks in advance
@@ElectronicmindsUK Thank You for that. I am using Bode100 (from omicron labs) for the impedance measurement I am still unable to measure ac resistance accurately

how to design switching frequency max 400Khz of gate dirve circuit in power electronics system.
The process would be similar to other gate drive designs, you need to set the drive voltage levels (uni-polar or bi-polar), drive strength etc and work out the power requirements of the gate driver - these often scale with frequency. 400kHz PWM is a time period of only 2.5us so you also will want to ensure good drive strength to keep edges as sharp as possible and minimise miller induced effects. The design of the gate drive will depend on the type of device you are driving too.
What is a good starting value to put in the first pass design for a CM choke,(for say filtering higher frequency >2MHz) , is there a rule of thumb value ? Another unrelated question - I have seen CM chokes connected to the two ends of a shunt resistor, in a design where the shunt resistor sits on one PCB and the voltage across the shunt connects to another PCB via cables (and is eventually connected to say an ADC)?
The value of CM Choke will depend on many aspects of the design and it is hard to give accurate guidance on this. However, as a good starting point, for offline isolated supplies up to about 100W, typical values are around 10mH. Start with that and then test/iterate. Remember that the CM choke (and any inductor) is only inductive over a specific range of operating frequencies. For your example of the CM Choke on a shunt resistor, this maybe to attenuate CM noise from the power stage (shunt) reaching the control board. CM noise is an interesting thing. It will find its way through all the parasitic elements of your design (i.e. the bits which you might not know are there) and it is key to understand the dominant coupling paths.
Thank you for sharing the brief insight
Very useful presentation ! Can you elaborate on why the sample frequency being same as switching frequency helps reduce noise ?
will this type of presentations continue in 2024?
Please do another one on the gate driver circuit design step by step with an example.
Hello, Very nice presentation! Could you please make a video on active inrush limiters using p type mosfets when there are bulk capacitors in DC-DC Converters? It would be helpful. Thank you.
sir what you done for entering the coordinates at starting. which key was pressed?

how we determine the PF?
Do you mean power factor here or something else?
Thanks for the nod towards FEMM and your tutorial efforts. I have been looking for opensource FEA, and this seems a good start. Having said this, in trying to apply the tool to an existing personal project I straight away hit some issues. Firstly I note that you have used an E core from TDK, this has a 'planar' symmetry. This I assume is most suitable for a 2D tool like FEMM. I have been running my LTSpice simulations for my LLC converter using a TDK ETD core. This has a sort of truncated axisymmetric shape. Have you specifically avoided such ferrite shapes. If not any tips about how to model them. If I choose an axisymmetric problem then the depth option is greyed out. Presumably the defined plane is spun around a vertical axis. But I would then have a shape which is nothing like an ETD core. I assume this is a basic limitation of a 2D tool such as FEMM?
he called my name :umesh" at 42:28
Great ! Thank you very much
Excellent presentation. You are sharing the state of the art of designing the converters with your valuable experience. I really liked all the videos and already subscribed the channel. I have only one suggestions that MATLAB has capability to make the scope background white from black and also you can change the width and colors of the plots. This will help viewers to digest it more easily. Other than that it is 10/10 presentation.
Thanks for this great feedback! It is really valuable to hear how we can improve our videos so thanks for taking the time to make these suggestions!
Great overview, much appreciated!
Thanks for the feedback Martin, much appreciated!
hi thank you so much about your knowladle. can ı ask a question, in 100khz we calculate 0.21mm skin depth. after that how we select optimal diameter you said 0.42.Do we multiply the skin depth directly by 2? in video 37m What I mean is, if there is a skin depth of 0.21mm, how can I calculate the cross-sectional area required to avoid skin effect?
Great seminar. Thanks, very informative. What is your thought with regards to the immersion cooling of power electronics components? It probably simplifies thermal design and increase the heat transfer. Are there particular things to watch out when considering the immersion cooling?
Thanks very much for your kind feedback. Immersion cooling of PE is a really interesting approach but not one I have practical experience with. What I think it will do is provide significantly improved heat transfer, especially from components which are harder to cool (e.g. magnetic parts). One interesting thing to consider is that the liquid is just a heat transfer mechanism so you will still need a way to couple heat out from the liquid and into the local ambient. There are some fluids from 3M which look interesting www.3m.co.uk/3M/en_GB/novec-uk/applications/thermal-management/immersion-cooling-of-power-electronics/#:~:text=Immersion%20cooling%20involves%20putting%20electronics,into%20the%20heat%20transfer%20fluid.
Any way to model flux transfer of a permanent magnet with FEMM? This is in reference to the memory effect when a coil steers the flux to one path or the other where it remains after the coil is de-energized. Also, how do I describe laminates with this 2.5D (x,y and an overal z) model?
Good question! I've not modelled permanent magnets myself with FEMM but there are some examples online of people doing this. Take a look at www.femm.info/wiki/PermanentMagnetExample. There are some other guides which cover modelling laminates in FEMM, take a look at www.femm.info/wiki/onedge
The design parameters are TOO BRIEIF outlined in 47:50/1:23 . Please indicate a justification for this choice. I realize that the presentation is for first time designers , hence the simplification is correct.
Hi, thank you for the presentation. Relay awesome content. I have a crazy question: from safety perspective it is not recommended, but if we want to see quickly only DM mode noise in the emi signature up to 2 MHz , should we see it if we disconnect PE wire between DUT and LISN?
Glad to hear that you liked the content! If you remove the PE wire then the common-mode noise will find it harder in the lower frequency ranges to find its way to the LISN. However, there are lots of other parasitic paths, mainly capacitive which will allow common-mode current to find its way back to the LISN and get registered. So removing the PE wire will most likely reduce the levels you see but the spectrum will still contain CM noise. You can achieve a better result using splitters to isolate DM and CM noise, check out this link www.analog.com/en/analog-dialogue/articles/separating-common-mode-and-differential-mode-emissions-in-conducted-emissions-testing.html
@ElectronicmindsUK how did you model the actual winding?
We found that you can model in two main ways in FEMM, either define a composite area which you then specify a number of turns to contain or draw them individually. Mostly the composite approach works well enough.
is there any possibility to research/work at your platform?
Sorry, not presently
Excellent
Thanks for your feedback!
Hi there, great videos I hope you keep them coming!? At 50:37 you show a bode plot with a 1A and 2A load. 1A bringing the converter into instability. Have you used PSIM before? Reason I ask is because generally I've been finding that if there is instability within the converter I can't seem to get nice bode plots like you are showing where you get to see that instability with such a nice clean trace.. Did you have to do any tricks or extra steps?
I started watching video just to take a look but I ended up taking notes and watching all video at once. Thank you for sharing those very useful pieces of information.
✌️ 'Promo SM'
Really great video, such a great initial kicker into FEMM! But is it just me or is the video of you clicking through FEMM so laggy that you don't actually see a lot of where you are clicking? It's weird though cause your voice is smooth and continuous, it's just watching you go through FEMM..
I'll take a look at the video for you. If it is laggy like you say then I'll check the settings on how it was recorded as it maybe too compressed perhaps.
This is such a wonderful series of webinars. I am actually a Masters student at University of Colorado, Boulder and taking courses from the authors of the book mentioned here. It's indeed a great Power Electronics textbook
@Electronic Minds regarding VOR with flyback design, it's usually something calculated/assumed very early on in the design process (maybe the first step or 2nd). With one output I get how you can get a sense of what VOR could be, but, when you have 3 or 4 outputs, how do you accurately estimate VOR?
Thanks for the comment. VOR is a primary side referenced value and is the same with multiple output flybacks. With multiple outputs, you have multiple secondary windings. In each case, the VOR is approximately Np*Vo/Ns where Vo is the output voltage each output and Ns is the number of turns of the respective output winding. Higher outputs have more secondary turns and the primary referenced VOR remains the same. I hope my explanation makes sense.
Nice presentation. Are the documents summarizing the type of compensators available for download?
I have them available but not sure I can attached them here?
@@ElectronicmindsUK yes, that would be helpful. Thanks
Does it help to put Y caps along with the common mode choke at the gate drive isolation barrier input and at the gate power supply input to provide a path for the common mode current to return back and reduce the loop area?
We have experimented with exactly that and I believe it does help. I don't have any data yet to confirm this though.
Excellent session...learned a lot ..Would it be possible to share the handwritten notes and mathcad files??
Glad you found it useful. Sorry but we don't release the notes or MathCAD files presently.
Great series. I remember signing up for it while at Nottingham and glad to see it on youtube now. I have a question - what is the path for the common current during the switching event? The capacitance from switching node to chassis is what is getting charged. What are the sources and the path for that current?
The source of the common mode current is anything which can result in current flowing in earth. In isolated supplies, we tend to look at the common-mode current generated from a fast edge on the primary winding coupling current into the secondary and also the cooling tabs of power transistors coupling noise from fast moving drain nodes onto heatsinks. Both these mechanisms ultimately couple current into earth via parasitic capacitances. It is also why sometimes earthing heatsinks directly can provide a direct path for common-mode current flow.
Thank you for sharing, really useful content, keep up the great work.
Hi, the analog control explained here is different from many application notes with better understanding. Thank you !
At the 23 minute, is it 1000 steps or 100 steps for 1Mhz PWM.
@@ElectronicmindsUK thanks for the response. I have another concern though. In the voltage measurement explanation, we doesnt need to use an isolation op amp evertime. We can just use a differential amplifier configuration with very low gain. It works well and the cost is low. Also higher performance than isolation op amps.
This is very good and helpful. Thank you very much for the time and effort. Could you please tell me what is the original platform/ website this webinar was conducted. Can you share the details. How do we get the next webinar link.
