@thomc2526منذ 2 سنوات I have to give a special class to my classmates and this videos saved my life, thank you so much for taking the time to explain step by step and for the animations they help a lot to understand :D 1

@ahoorapersia4698منذ 2 سنوات Hi . Thank you for this explain. I have a question: In a smps device that I want to repair, there are 2 SRD (3pda 60), step recovery diode, and there is not pulse transformer. Please explain how that diodes work.

@devbhavsar8025منذ 2 سنوات the output input voltage relation needs some editing, it should be 0.5Vi instead of 2Vi.
Well done for your hardwork. 1

@Dc_tech386منذ 2 سنوات Thank but I have burning questions if I series two 555 timer can I use the two output signal for h bridge inverting for high and low with the two 555 timer id="hidden4" class="buttons"> I see a circuit of that in a h bridge motor drive but not on inverter so I want to know if the same design can use a transformer for inverting ....وسعت

@jayshah4413منذ 2 سنوات Will freewheeling happen at primary side? How primary side current is increasing and decreasing drastically from zero?

@SefaOralzمنذ 2 سنوات Thank you very much sir, I appreciate !
@

@mateusztrzmiel8979منذ 2 سنوات there is a minor mistake. Currents of diodes will look slightly different. Due to inductance of a transformer they cannot change immediately. So if initially ID1 was 100A and ID2 was 0A, they will respectively decrease and increase until they eventually reach L1 current. ....وسعت

@frankcole3196منذ 3 سنوات As Subhojit Das says, with both Q1 and Q2 'on' . even briefly, the Vin DC supply is short circuited (through the Mosfets) and a very high current, id="hidden6" class="buttons"> often exceeding the Mosfet specifications, can flow. This is called 'shoot-through' and has to be avoided. Dead-time in the turn-on and turn-off is introduced to prevent this situation. ....وسعت

@panditamol12منذ 2 سنوات I have issues with my circuit ..would u help me
I hv designed half bridge topology based smps
.. i already implemented dead time in two id="hidden7" class="buttons"> gate input
Bt when I check the input of primary of transformer then dead time does not present
And if I reduced the duty cycle of gate .still transformer primary still gives 50% squre out with no dead time ..will u help me ..thank u very much ....وسعت

@052_davidbennysetiawan7منذ 4 سنوات Can i know how to calculate the value of inductor and capacitor in the output, so i can design this converter 1
@

@ruchikumari6996منذ 4 سنوات Hey you have taken input voltage as Dc right?. so how does it support induction in transformer.since we have been studying since btech, transformer works in ac only?

@freedomisfood6966منذ 2 سنوات excuse me may be i am in trouble.but in animation current crossing from capacitor in wich the dc current dont cross from capacitor.first mosfet charge id="hidden9" class="buttons"> second mosfet and current is open because capacitor is charged .when mosfet nuber2 is closed the capacitor 2 discharge .and continued.but why the mosfets must be open in one time .one is closed other is opend.and revers.!!!!!!! ....وسعت

@garinanggara8358منذ 3 سنوات Sir, what if there is no current path at secondary? I mean open circuit.
Does the MOSFET will heat up bcs of saturation?

@danalex2991منذ 4 سنوات Why is Vo = 2 x Vin x D x turn ratio ? I can understand Vin x D x turn ratio . But I don't understand how that 2 came . I thought when you are connecting id="hidden10" class="buttons"> from center tap to one end you will get only half the total secondary voltage . So shouldn'it be 1/2 x Vin x D x turn ratio. ? ....وسعت 1

@kubajz2257منذ 2 سنوات No, the problem is that the MOSFETs would short out the power supply. 1

i already have a background on rhe half bridge feedback thanks to you but it is not enough for me so far

@abdurrahmanenic625منذ 2 سنوات V0 should be equal to Vin*D*Ns/Np instead of 2*Vin*D*Ns/Np

@johnaweissمنذ 4 سنوات Plz explain advantage/disadvantage compared to Full Bridge converter.

@paramanandprajapati3867منذ 3 سنوات why are we using Schottky diode, why not simple diode?

@subhojitdas108منذ 3 سنوات so far I know the dead time applied in PWM is due to sc of source ..not the tx saturation. you need to check that point
