Heatsink grounding
« on: September 29, 2023, 04:33:32 PM »
In all the resources I see it's recommended to connect your driver enclosure, igbt heatsink, etc. to the rf ground. Why is that recommended? It seems like it just lets an hv pulse shoot through the igbts or kill the driver if you have a bad rf ground. I know that if you leave them floating, they'll pick up some voltage, but if it's enough to be dangerous why not connect them to mains ground directly or with a resistor?

My preference is both, to mains ground and to counterpoise (presuming RF ground means the same thing).
