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.<>
