SUPER-EFFICIENT SINGLE-STAGE ISOLATED SWITCHING POWER AMPLIFIER

摘要

A super efficient single-stage switching power amplifier is realized by not incorporating a rectification process in its power conversion loop while incorporating a bidirectional active clamping circuit to not only remove or maximally reduce otherwise occurring disruptive ringing and spikes but also convert the energy otherwise associated with the ringing and spikes to return energy that goes back to the DC power supply.
