Abstract

Neutral beam injection for fusion requires DC megavolt power sources at several amperes. The conventional methods of using series or shunt fed multipliers cannot provide the current, whereas the 60-Hz coupled transformer method is difficult to modularize because of size and stores excessive amounts of energy. A technique which borrows from several technologies has been investigated and shows promise for a satisfactory solution. This technique uses resonant multistage high frequency (100-kHz) series coupled ferrite transformer with rectifiers to produce megavolts at several amperes of current. Modularity, high efficiency, and low energy storage are desirable features of this power source.<>
