Problem inverter egs002
« on: June 23, 2018, 11:57:48 PM »
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?

Hi,

In the beginning it was soon realised that the EGS002 board was workable up to about 3kW if you were lucky.

I recall Oztules taking a razor blade to that LM393, on the EGS002, but then there were start up issues, so hence the New OzControl board.  I am now on a mark 15 OzControl PCB.

For the info on the EGS002 board to the OzControl board   see.........

Everything is possible, just give me time.
