Abstract :
Pulse width modulation (PWM) is extended to cases in which multiple signals are to be encoded into 2 single data stream, while still supporting. all the requirements of power conversion. This permits lossless recovery of multiple signals with a single set of converters. The approach has applications in digital PWM amplification of audio signals and in three-phase converters. It permits a unified AC link converter, for example, to conveniently deliver multiple output signals.
