HV Pulse Inversion for high power application.

[engineer_a]

Hi Everyone,
I want to know that how a HV and high power positive pulsed can be converted in to negative pulsed.
I am asking in reference to Pulsed power modulators for Kylstron or Magnetron operation.
I have seen some designs in which AC power is firstly converted to DC and then Specially designed switching network converts it into pulses and then these pulses are converted to High voltage pulsed (using pulse transformers, i Guess). Now what if some application need Negative pulses instead of positive pulses?:?:

Regards.;-)

Perhaps you could use a 4 MOSFET H-Bridge to act as a pulse steering circuit. The pulse could be made positive or negative on will.

A general method to get a negative output, is by reversing diode orientations.

" voltage pulsed (using pulse transformers, i Guess).", change connections to the transformer? Are you just modulating the mod anode?, If so just use AC coupling (BIG C, HIGH volts!!)
