Paul , i guess i'm just lucky! most thing never work first time for me
Power factor won't be great on this version but i'm working on a boost pfc frontend that will bring it up near unity. I'm also considering running it on 3 phase where pf is not so much of a concern.
I took it up to about 3kw later on today then had a mishap! The battery sensing resistor got hot enough to burn through the insulation of the ground sense wire. Bang. And yes i got it on tape Took out the igbt , driver chip and dc dc converter. Vaporised the sense resistor. Got the bits swapped out and its now up and running again.
Here is some video from earlier tests :
I have to say I'm very impressed so far. No temp rise at all , very stable. I would like to identify the weird noise I observed on the scope in the video. Any ideas?
