  Thanks for the video. I had a question about how the power flows from one bridge to another bridge when the same gate pulse is applied to both primary and secondary side switches. Could you please explain?

• 
  @manoA98A18 күн бұрын

  During the Turn On time, in which M1 and M4 are On the current will flow in the positive verse, from left to right in the tank llc. Then the current goes in the secondary side and will follow the same path of the diode (so the first mosfet on the top left will be on). Imagine to replace the passive diodes with the active mosfets. During Ton, M1 and M4 are on on the primary, and the other two mosfet are active on the secondary (Top left and bottom right) like the diode were active passively. I explained this in the video before designign the synch rectifier

  @@rajeshsethuraman1383 If you ever design this converter in practice, there will actually be a time delay lag between the first bridge and the secondary one. It's not 100% simultaneuous. Plus, when dealing with HV and probably SiC device, there will be additional loss to the discharge of the Cds at each switching cycle which has to be taken in to account. Driver design and auxiliar power supply for the driver are not shown in this video. In real life you will need flyback or push pull to generate 15/20V for the power supply or your drivers, both used for the first and the second bridge

  @Gattuser2 ай бұрын

  Thanks for the video. Few comments. 1. The initial issue with the simulation (why it was so slow) was indeed caused by the high side driver, as E1 negative terminal was connected to GND, while it should have been connected to the L1 (and that's what you've done with MOSFETs latter on). 2. Efficiency calculation didn't work, because you have to include "param" keyword before using math on symbols thar are not defined in the circuit. 3. Your transformer polarity is wrong, it is a two switch forward converter (and not a two switch flyback), hence polarity of both windings should be the same as energy should get transferred during ON cycle.

  Hello, Thank you for you explanation. I have a little queston in minute 5:07, you've wriiten Vg = 12V + Vdd, why is this correct, normally Vg must equal to capacitor voltage which is 12V and not 12V + Vdd Thank you

• 
  @manoA98A2 ай бұрын

  Hi The point of the bootstrap Is to make the VGs voltage indipendent from the load. The VG voltage charges to 12V+Vdd according to kirkoff Law during the turn on. Because Vs Is at VDD since the MOSFET Is on. So the VGs Is 12V and in fact it's on. That part of the video Is Just to explain how the charging system work, but the real implementation of the bootstrap Is explained later. You normally connect the bootstrap capacitor After the diode and in the source

  Ciao, ho provato a fare la simulazione usando la DC-SWEEP sulla Vin per ottenere il plot dell' isteresi ma mi da solo uno dei due rami. Ho fatto variare la Vin nello sweep da -5V a +5V e poi una seconda simulazione da +5V a -5V. In questo modo però visualizzo solamente mezzo ciclo di isteresi. Ho anche provato a inserire una lista di valori nello sweep per simulare i due versi cambiamento delle tensione (list -5 -1 0 1 5 1 0 -1 -5) ma sballa completamente. Non conoscevo il metodo di cambiare la variabile del plot che hai utilizzato tu, inoltre nel tuo modo non sembra possibile cambiare gli estremi della V(in) . Sapresti rispondere a queste due domande? Ti ringrazio

• 
  @manoA98A2 ай бұрын

  Certo, ed è giusto che ti dia solo un ramo, perchè tu la caratteristica del comparatore la fai da sinistra verso destra, e tu segui "le freccie" della caratteristica, non ottenendo quindi "il rettangolo" dell'isteresi. Se tu parti dal negativo e vai verso il positivo, allora vai da sinistra verso destra. Se parti dal positivo e vai dal negativo, allora segui le freccie al contrario ma in ogni caso otterrai solo uno dei due rami 1)Se vuoi ottenere entrambi i rami, non devi fare DC sweep, ma mettere un seno in ingresso e nel grafico del plot, fai tasto destro dove c'è scritto time e metti V(in). (Naturalmente devi aver chiamato il nodo (In) altrimenti non funziona: se segui il video passo passo otterrai il bellissimo retttangolo dell'isteresi. 2)Si, è possibile cambiare gli estremi della V(in), perchè ho messo un seno con ampiezza 4V, quindi i valori cambiano tra -4 e 4. Puoi mettere un seno tra -10 e +10 se vuoi ampliare i tuoi estremi

  Thank you for watching my video If you are working with PFC, your configuration Will probably be a boost converter, with Low side switch That MOSFET, should switch following the 100Hz rectified pulsed line voltage that you have at the input. Basically, you Will have two ripple in your circuit: the FSw ripple at your switching frequency, like 100kHz and the 100Hz Now, for the control, you Will probably have to design a type2 compensator, because boost converter have the inductor on the input side and they don't need type 3 , in both cases of voltage and current control. Remember that type2 control Is basically a PI control Anyway, I intend to make more videos about PFC in the near future, so stay tuned
