I'm trying to control LLC tank with full bridge MOSFET DRV8702-Q1EVM. LLC tank is connected betwen pins SH1 and SH2. I'm using other MCU with two PWM channels.
The only things have issue is with measuring the current on shunt. I put VREF to AVDD and It seems the negative current flow from LC tank?
I got to much negative voltage on SO pin Any solutions to avoid negative SO voltage? Possible that DRV8702 was not the best choice for driving LLC tank but other things Works perfectly?
