ABSTRACT:
Apparatus for converting a single-phase power supply to multi-phase operation in which at least one phase of the multi-phase supply is generated by applying the single-phase to the input of a bridge network, each arm of which contains at least one switch device controlled by external circuitry to give an output waveform from the bridge network which contains a fundamental component of the single phase which is out of phase with the single phase by a predetermined phase angle. The output waveform may be filtered to eliminate unwanted harmonics.
