Soft Switching Hard Switching vs Resonance | Resonant Converters | Power Electronics

This power electronics video presents an introduction to hard switching and soft switching and how resonant converters and circuits can be utilized to minimize such power loss . Inadequate switching is the main contributor to power losses in power converters. As the switching frequency increases, the average power loss in the device increases as well.

I Browsed a lot but couldnt find the exact concept on this resonant converters but now im happy that i have gained some knowledge on this topic keep doing more videos like this and make us happy THANK YOU SIR.

[@burgenkinger2856]

Fantastic!! Thank u for your efforts!!

[@mohammedammari9549]

Amazing. Thank you Ahmad and Br from Germnay

[@raefsiam]

Good work Dr. Ahmed

[@afonsomanuel1585]

Great video.

[@Sanghun_Kim]

Thank you for your lecture

[@Tobinio1]

this is gold

[@SefaOralz]

Above the resonant frequency, rectifier diodes or transistors (whatever used) can not achive ZCS means not soft switched and it will increase switching loss. What do you think sir ?

[@zakialkama5395]

thank you

[@tze-ven]

Nice!👍

[@issaalaji3756]

Thank you for this explanation. Just a small remark, i think that you had to emphasize that the resonance occurs (inductors and capacitors cancel each other) at certain frequency (resonant frequency)

[@Aboudy1989]

Already had been said

[@raefsiam]

thank you very much

[@frajbenarab5523]

please sir,i was wondering if you can tell me how we can achieve ZVS in LLC converter with GaN half bridge topology and GaN don't have a body diode,so where does current flow to make voltage across the device zero before turn it on.thank you

[@trunke1085]

Why would we want to completely filter the higher harmonics? Dont thier energy transfer to the output as well?

[@2ndgameX]

I'm no expert, but I think the purpose of filtering out the higher harmonics, and therefore aquiring an almost sinusoidal current, is to make ZCS (Zero-Current Switching) possible.

[@Egzoset]

That's a simulation, right? ...
