Design of active ripple filters for power circuits operating in the 1-10 MHz range

A fundamental analysis of active ripple filters for powder circuits operating in 1-10 MHz range is presented. The improved understanding derived from this analysis allows filter circuits with gains five to ten times higher than previously reported to be built. Besides providing further reduction in the size of 1 MHz ripple filters, these higher gains make the active filters valuable for power circuit switching near 10 MHz.<
