At 2kW, whats the highest Vout LLC converter you know of? (Vin = 400VDC)?
Not talking about nay use of Cockroft Walton multipliers.
ie, how high in voltage can you get, without resorting to Cockroft walton.

And presumably you can get standard ECW cheaply coated so it has isolation rating to 20kV?

Hi,
For 2kW output, what is the highest voltage output LLC converter you can do?
Vin = 400VDC.
Anybody tired doing a 2kW, 8kV LLC with 8 series'd LLCs , each of 1kV output?
Presumably best to do them from -4kV below earth to +4kV above earth?
Custom bobbin....plastic spacer between pri and sec.
Easy isnt it?

Primarys are all paralleled...secondaries are stacked.
