Hello,
I am designing a new PCB for LLC converter and I just finishend laying out the H-Bridge for the input section. The PCB is 4 layer and primary side is rated for 500V/6A. Switching freq. is around 100kHz. I used TO 247-4 MOSFETs for H-Bridge. I named positive input to HV+ and negative...
Thanks for your feedback. I am waiting to receive the new FETs from the supplier and try your suggestions out. In germany everything takes time :)
I will keep you posted about further developments.
I will give it a try. I found this one in my lab...
Thank you very much for your reply. Its interesting to hear your point of view.
Here is a pic How my Mosfet H Bridge looks like ( they are mounted on a heat sink) and
here is how I connected to take the measurement of V_GS of Upper and lower MOSFET of the H-Bridge.
Bellow are also two...
Here is a problem I encountered in the Lab today and would love to hear your thoughts about it.
I was testing a LLC converter I designed under high voltage (500V) and after couple of test under low power (100kHz, 300ns dead time), upper MOSFETs (SCT3160) of H-bridge got damaged. Both of the...
