Really loved the video, can PSFB be used for step up converters, what are the drawback of using PSFB for a step up instead of step down.. also what challenges do you see them when using at higher power rating 20kW, 50kW or higher. Thanks in advance.
Yes can be used. The voltage spikes across the secondary side diodes due to its reverse recovery time and transformer leakage inductance becomes big concerns
In a transformer, as the voltage goes down, the current goes up according to the turns ratio. However, in DC-DC converters, the current does not increase when the voltage goes down, but the current is supplied according to the load. So isn't it against the principle of V1I1=V2I2?
sir i want to increase the voltage from 400v to 1000v its is possible by high frequency transformer ? and again full bridge recrtifier. bcz i need 1kv at output
Hi your video is amazing. I am a big fan of you. Can you do the simulation of LLC & CLLC resonant converter. Nowadays these topologies are used in advanced systems. Please do the simulation so we can easily understand
If you like my work, please do consider subscribing to this channel.Thank you. th-cam.com/channels/58DFky5Fm9AxH9UmWHHYmQ.html
Very good explanation
great discussion
Best simulation video ever seen 👍
Sir Can u pls explain me how to fined values of Kp Ki for any simulation? How u determine those?
Sir can u please give the formula for calculating dead time for both legs of the phase shifted full bridge converter
it is worth attending. sir.
Thanks
can you please explain how to calculate the peak values for these waveforms
Hello Sir, Please prepare videos on Full-Bridge DC-DC Buck/Boost/Buck-Boost Converters.

Please provide source for each video you make, sometimes we need more information. If you can do that it is really appreciated.
make same video for dual active bridge converter and quad active bridge converter
Great work in explaining this topology. Does PSPICE or LT SPice has Spice model for the UC3875 PWM ? TIA
Sir can u explain how to find kp and Ki values
4:56 why D is n*Vi/2*Vo and not just n*Vi/Vo ? where does the 1/2 constant come from in calculing D?
50% duty cycle. That is half of the period. Basically, half of the time we charge the inductor, and the second half we allow it to discharge.
superb
Thanks
Hi, thx for educating your viewrs, how do I contact you

In a transformer, as the voltage goes down, the current goes up according to the turns ratio.
However, in DC-DC converters, the current does not increase when the voltage goes down, but the current is supplied according to the load.
So isn't it against the principle of V1I1=V2I2?
To stisfy the equation, power has to be constant
Could you give the reference link of this converter design and analysis?
can i use this converter for pso mppt tracking using partial shaded conition?
𝐷 of inductor=(𝑉𝑜𝑢𝑡_𝑟𝑒𝑞𝑢𝑖𝑟𝑒𝑑/𝑉𝑜𝑢𝑡_𝑚𝑎𝑥)×(1/2).May i know how is this equation derived.
sir i want to increase the voltage from 400v to 1000v its is possible by high frequency transformer ? and again full bridge recrtifier. bcz i need 1kv at output
Yes I have simulated and working on hardware with phaseshift. What is your application ajeetdhkar@gmail.com
please post WECS with PMSG
will try to make it
frequency at output filter inductor is twice the switching frequency
Put the video about LLC CONVERTER
Hi your video is amazing. I am a big fan of you. Can you do the simulation of LLC & CLLC resonant converter. Nowadays these topologies are used in advanced systems. Please do the simulation so we can easily understand
Will try
Hi, can you help simulate phase shifted pwm on ltspice?
Please do soft switching in converters
sure👍
Can you simulate about PV and battery single phase back to back converter connect grid ?Thanks！
Will try to make
Can this converter be used for boost operation?
Yes. But it mostlly used for buck operation
transformer ratio a = V1/V2 right?? 3:41 is not right??
It can be V1/V2 or V2/V1. Accordingly u have to change the other equations
Can you simulate about PV inverter connect grid single phase?
sure. will upload very soon
Please make a video on three phase analysis using UPQC
will try
