Abstract
A high power AM-band transmitter amplifier comprises four switches in an H-Bridge configuration and operates by adjusting the duty cycle of the voltage waveform on a transformer. The duty cycle is adjusted by changing the phase relationship between the diagonal switch pairs. An embodiment of the amplifier operates efficiently by the addition of a current source that may comprise inductor and capacitor circuits to assure zero voltage switching of all the switches. The inventive H-Bridge configuration can also be utilized in a phase modulated power supply.
