Abstract:
1. A method of converting a single phase power supply source into a three phase power supply source, wherein said single phase power supply source includes at least one input active and an input neutral, and wherein said three phase power supply source is a three phase star having three output actives and said input neutral as its common neutral, said method including the steps of: using said input active as a first output active of said three phase power supply source; and, creating a second and third output active of said three phase power supply source using part of said single phase power supply source and/or an external power supply source, at negative polarity and at half magnitude with reference to said first output active, combined with at least one phase shifting inverting circuit which generates its output at 90° at a magnitude of 0.866 with reference to said first output active.
