Hi all
I need some advice with regards to repairing a pure sign wave inverter
I have a new spwm. (EGS002)
4 new IGBT’s and all new associated resistors and diodes
The spwm is getting a good 5v and 12v
The IGBT’s are getting a good 380vdc
When powering on, I can hear the transformers buzzing for 3 seconds and I get a peak of 8vac from the output. After these 3 seconds, the spwm shuts down and flashes the low voltage code (not that I need it to know that 8v is far too low)
Why am I not getting 230v even tho the IGBT’s are being fed with 380vdc?
I’m really at a loss
