#pushpullconverter #DCDCconverter 0:00 Index 00:45 Circuit diagram 01:35 Working 03:08 Waveforms of the working 04:07 Design parameters 04:29 Selection of Core The push-pull converter is one of the oldest topologies and It can give multiple outputs, which gives isolated DC-voltage from the input. Output voltages can be higher or lower than input voltages as we change the winding of the transformer. This videos contains all the steps which are necessary while designing the Push-pull converter. This tutorial is divided into several parts for better understanding. this part of the video contains the description and working of push pull converter, it also contains the step in which we select the core for transformer which is used in this converter.

@eamonhannon1103العام الماضي Goog video ! Nice pace . Well presented .

@shivakumart2106منذ 5 سنوات very good job..thank you for ..good explanation

@palanir273منذ 2 سنوات Hi, rally it good thanks you so much. And please tell how to select topology and what are the critical parameters consider for converter topology selection. id="hidden1" class="buttons"> E.g 48vdc input, o/p 12v/10A isolation cccv driver for charging application, this we can design flyback or forward or push pull or half bridge. But how to select for topology for start up. Pls help me ....وسعت

@waterfuelمنذ 2 سنوات Where can I purchase a 12v DC to 28v DC step up converter about 200Watt 6amp output, that is ISOLATED with separate transformer contained?
@

@randompanda5134منذ 5 سنوات By any chance, do you know maybe what happens to the secondary voltage and current if you make an extra output voltage with 2 extra diodes in reverse? id="hidden2" class="buttons">
Example: Output voltage is 70V but by placing 2 diodes and an extra filter I also make -70V.
Since you don`t have an extra winding i'm confused. Does the current increase 2 times? the voltage? Or can i just assume the single +70V for the calculation of the trafo?
Good video btw! ....وسعت 1

@elmnaoirfer3751منذ 2 سنوات Hello, does the frequency change, through feedback, or is the pulse width the one that changes with a fixed frequency, to fix the output voltage, to the required voltage, thank you very much 1
@

@sovietrepublic38منذ 6 سنوات Except for the turning number of the primary and secondary coils, the pulse width of the input will also effect the voltage, right?
@

@fernandohood5542منذ 3 سنوات I have a similar circuit and I am wondering if the high voltage spikes on the secondary are normal.

@Flux1905منذ 6 سنوات May i know what is the feedback on the circuit?The one that connects the load and the mosfet

@Dc_tech386قبل 10 أشهر Hello I hope you can reply to my comments i am having issues with push pull converter at high dcv from 40 volt and up my push pull converter at 31khz mosfet id="hidden4" class="buttons"> burning it self up at zero load I use a 6 amp totem pole driver and pnp and diodes to drive the mosfets properly but the higher the voltage get the faster the mosfets burn up I use irfb4110 mosfets rating for 100 volt and hy4008 rated for 80volt any voltage above 42 volt the mosfets slowly increase temperature and burn up at zero load even when I reduce amp to 1 amp the mosfets still burn up the gate voltage is 15 volt pulse ....وسعت

@revivalclipمنذ 5 سنوات Really nice video, and great explanation too! I'm currently working on my final year project on push pull transistor converters. I'll love to know what kind of circuit can be used as feedback in your design 1
@

@SigmaCمنذ 3 سنوات what is the graph that you used to select the core?
@

@karthickc7397منذ 5 سنوات what is the core selection for 3KW output
can you please send me the core details
@

@kamleshchavan7451منذ 2 سنوات Sir please make video on astable multivibrator , explaining it's working in simple way
@

@smartups1منذ 6 سنوات Please design an pfc with uc3854 and detailed design about pfc inductor how properly select inductor material. 1
