ABSTRACT:
A minimum pulse width switching power amplifier utilizes digital logic for generating a control pulse having a pulse width at least as large as a fixed minimum period of time when a base control pulse generated by a comparator has a pulse width at least as large as a given value. A high power switching output stage is switched between different voltage levels under control of the control signal generated by the digital logic so that an average actual output of the amplifier is equal to the desired output.
