- in this video {842} Single Switch Forward Converter Topology, i explained the single switch offline forward converter topology, how forward converter works, it is isolated buck converter, using single switch, it can provide up to 250 watt output power. forward converter transfers energy directly the from the input source to the load
during the on-time of the power switch. During off-time of the power switch, the energy is freewheeling through the output inductor and the freewheeling diode. A forward converter can be made by single switch structure or with a double switch structure, according to the way the energy
stored in the transformer primary inductance is demagnetized.
forward converter is a transformer based isolated converter, it based on the basic buck converter topology. In a forward converter, a switch is connected in series with the transformer primary winding. The switch provides switching voltage at the transformer primary winding. normally step down transformer is used to step down the primary voltage, and provide isolation between the
input voltage source VIN and the output voltage VOUT. when the switch is ON for a period of t-on , the dot end of the winding becomes positive with respect to the non-dot end. Therefore, the output diode becomes forward-biased As the input voltage are applied across the transformer primary winding, the magnetizing current IM increases linearly from its initial zero value to a maximum value. The total current that flows through the primary winding is this magnetizing current plus the inductor current (IL) reflected on the primary side. in off period the tertiary winding or reset winding demagnetizes the core. and the freewheeling diode in output side provides load current, resultant of the collapsing magnetic field of the inductor

it is interesting to know. It is well explained. 👍👏👋
thanks a lot for your valuable appreciation
please accept my best regards
Like very interesting amazing wonderful informative video good job thanks 🙏 for sharing
beset regards
You are my univercity....thanks a lot sir ji....
It's my pleasure
Very simplified explanation,excellent teaching ability…..thanks
Sallam ALIKOUM ! On apprend beaucoup avec vous! Encore merci !d'ALGERIE
Very well informative I learn why my converter was blowing diodes and igbt and mosfets now I use 114 volt with a 600 volt rating igbt and 200 volt rating mosfet and 200 volt Shockley diodes so thank you very much for the information
I am happy that you explained the difference between flyback converter and forward converter. Very important that in forward converter the current in the coil is higher compared with flyback. Thank you again for everything. 👍👏👋
best regards and special thanks
Ottimo spiegazione. 🤩🙏👍
thank you for diagram and explanation.
it is my pleasure
Excellent! I don't know a better word to describe this video. Thanks.
best regards and special thanks
Thank you for good explanation
I hope to see practical experiment
You are a good teacher !! Thank you, sir.
You are welcome!
good information thanks sir
best regards
Thank you and very well explained though in reality it is pretty much complicated.
best regards and special thanks
Thank you very much brother a very clear and simple to understand thank you request for next level push pull topology

Dear Mr. Haseeb. I am from Sri lanka.I respect and gratitude for you, because you have done very valuable and superb tremendous service to the electronic field.Your endeavor is very very successful.I also have attempted to design boost converters, but i was unable to get regulated output voltage. In (no-load) condition, it was success. But it couldn't drive the load.(output voltage became zero level when load is connected).I hope your further clarification about this matter and calculations and design explanation about boost-converters in future videos. Thank You.
Great!
Excellent
Thank you so much 😀
Thanx nice 👍
Most welcome
great
it is my pleasure
Hi. I have watched a lot o video from to try to understand how to winding smps transformer. Can you make a video showing how to winding the flyback and forward converter? Thank you very much.
Excellent as always! Thank you! A quick question: when switch is on and there is positive voltage on the cathode of the capacitor, does that not damage the capacitor?

sir i have a question?why is it when u measure amps. of the unit goes up when plug in small voltage than higher voltage.for ex. led tv wjen plug in in 110v is higher current than u plug in 220v.how is that happen?when ohms law said that voltage is directly proportional to amps.hope e make a video for it.
Sir we want Gate Driver Transformer explain and how to winding Gate driver transformer ?
how to Design transformator forward topologi?
are you from India?
no I am from Pakistan
Brother,all you have posted so far is for10 please your trnslation in SERBIAN.
