   Why?

-Phil LaBudde "

With modern semiconductor devices (MOSFETS, IGBT's, etc.) and modern magnetic materials devices for converting power forms (DC to another voltage DC, DC to AC) can be made much lighter than those using AC frequencies such as the universal aircraft standard of 400 Hz. Modern trend is to rectify the output of the AC generator to produce +/- 135 VDC and transmit it around the vehicle where it is converted into the final power form at the using device. Almost universal for new systems.
