Re: PIP inverter repairs and hardware modifications

It looks doubtful to me that the PCB can be repaired. All the charred PCB material is conductive and needs to be removed from the circuit. You might be able to move some parts to a daughter board, perhaps using through-hole equivalent parts on veroboard or similar. If the transformer or multi windin...

Yes, I was thinking that recently. It has to be the 138 years of experience and refinement, and mass production.

Re: PIP inverter repairs and hardware modifications

I have checked (in circuit) all IGBT and their driver (voltage drop in diode mode, and resistance) comparing them with the other inverter I have So I's suspecting the gate driver chips. That's why functional testing (even just at DC) is a good idea. It's really the only way to test the gate driver ...

Can I run it with one of the NTCs disconnected ? Yes, I believe so. You'll likely get a temperature warning, and it may stop you from getting full power from the DC-AC converter. ( polarity ? ) These are Negative Temperature Coefficient resistors; polarity is not an issue. What kind of NTC are thes...
