ABSTRACT:
An audio signal tracking power converter has a master converter and a slave inverter which are connected in parallel to a dc power source that is to be converted and provide a first and second ac output signal. The first ac signal and the second ac signal are combined and converted to a dc signal that tracks the input audio signal. The master inverter is controlled by a free-running pulse generator which pulse-width modulates the first portion of the dc power that is converted to the first ac signal. The slave inverter is pulse-width modulated by pulses that result from the comparison of the audio signal that is to be tracked and a reference signal generated from the pulses from the free-running pulse generator.
