Good evening everyone.
I recently made the inverter board of 15kw, but I'm having a problem, when I connect the board, I realize that the gate outputs "HO" have increased voltage, which ends up burning the mosfets. I noticed that there is a voltage buildup on the two transformer outputs, returning voltage on the "VS and VB" terminals of the ir2113 drivers, which increases the voltage of the "HO" outputs of the ir2113 inverters. What can this be? Can someone help me?
