Hello guys! I'm using this cirtuit to power my big drsstc:
I need to improve the filtering to improve reability. I was getting some voltage spikes at the boost output because the EMI induced on the long DC bus.
What you think about this:
Another filter at the boost output will help to remove the EMI induced on the bus.
I was running the boost with no line filter at the AC input. Now I'm thinking to put one. The other inductor and capacitor at the AC input are to reduce the 15khz ripple that the boost puts on the line.
1 - I have doubts about the filter at the output of the boost. I was wondering if he should be placed opposite or the way I drew.
2 - I'm using a separate ground for the secondary is that good or bad? I was thinking of putting a small capacitor between the ground and the grounding of the secondary filters, connect the two together does not seem good. But leaving separately seem to be too bad.

What are you using for an output filter capacitor on the PFC boost?

At the output the boost only have the 3200uF big capacitor
