Below is the Half-Bridge LLC Converter Example from SIMPLIS.
I would like to observe the loss from the low side MOSFET.
I want to compare the ZVS and Non-ZVS conditions.
I am curious about why the circuit operating in ZVS condition the power loss in Q2 has a negative spike in there, but there is no negative spike when the circuit operating in non-ZVS condition.
Does anyone know how to explain it?
