hello
i am using ir2110 as mosfet driver and pic18f2431 microcontoller to drive
3 phase 110vac 2amp motor.
my design is onpen loop no. dc bus monitor and not current feedback.
board is just on off motor. board is working fine from last 1 year.
my problem is some time 2 mosfet shorted 90% half leg may be U/V/W.
how i can protect mosfet to not shorted.
how by monitoring dc bus i can protect. i can not implement current monitor
due to designed pcb.
please help me.
