Hello!
I’m trying to make switching loss model for partial ZVS or ZCS converter. I believe achieving ZVS means they don’t have turn-on loss but how about partial ZVS and ZCS converter?
I already put it each legend, we have gate signal, Vds voltage/current waveform and last one is switching loss.
as we can see there, there is NO turn on loss. even there are still voltage on the Vds, also there is no current on the MOSFET. It means basically operated like partial ZVS or ZCS.
So I was trying to understand of this behavior, because there is no energy model on the Turn-on loss table especially 0A condition(as we can see below loss model). I think that’s why we can’t see the turn-on loss on the scope. This is because there is no current on the MOSFET at the turn on moment, because it operate like ZCS or partial ZVS.
So do we already have solution for this one? Because so far, I’ve check each energy model, which made by MOSFET company also does not have energy loss @0A on their loss plot. Please give me any idea of this, It would be really helpful to make loss model.
