Abstract
A full-bridge amplifier that is able to provide power to all types of loads. The fill-bridge amplifier according to the present invention recovers reactive energy produced by capacitive loads instead of having the reactive energy be dissipated in the switches of the amplifier, thereby causing device failure. In one embodiment, two inductors and four diodes are added to the conventional full-bridge topology. Furthermore, a full-bridge amplifier according to an embodiment of the present invention is able to operate over a broad-band of radio frequencies.
