ABSTRACT:
A high-efficiency analog power amplifier is disclosed. The amplifier utilizes pulse-width-modulation ("PWM") signals to operate electrical switching devices coupled in series across a d.c. power source. A resonant circuit coupled to the transistors periodically places zero and non-zero voltage levels across each transistor. The frequency and width of the PWM signals are relative to the components of the resonant circuit--enabling each transistor to switch off and on only when zero volts appears across the transistor.
