High voltage series resonant inverter ion engine screen supply

Anticipated future spacecraft requirements have motivated research on high power, high voltage dc to dc power processors. Therefore, a LC series resonant inverter utilizing silicon-controlled rectifiers (SCR's) or thyristors as power switches has been developed as the main power stage of the ion engine power processor over an input of 200 to 400Vdc, and an output of no load to 2.5KW.
