I have a problem in my 3 phase inverter circuit output. Below, i've attached an image of my circuit. As you can see, i have 3 outputs. There are R, S, and T. So, i've measured line to line voltage across the 3 outputs. But i have problem with S-T output. With 20 VDC Supply, i got R-S voltage approximate 7 V, same as R-T, but 1-2 V for S-T. I don't know where's the problem, i've checked my MOSFETs and they're all fine, i've no MOSFET heat problem too. But still i don't know where is the problem. Could anyone help me, please?? Thanks in advance.
I've attached my gate driver circuit too, maybe there is correlation between MOSFET bridge circuit problem with gate driver circuit. (i am using IR2112 IC for my gate driver circuit).
