<p>Disclosed is an apparatus for converting a single-phase power supply source into a three-phase power supply source. The single-phase power supply source includes at least one input active and an input neutral and the three-phase power supply source is a three-phase star having three output actives and the input neutral as its common neutral. The apparatus includes terminal means for connecting the input active to the apparatus to be used as a first output active of the three-phase power supply source. The apparatus also includes phase generation means for creating a second and third output active of the three-phase power supply source. The phase generation means uses part of the 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 degrees at a magnitude of 0.866 with reference to said first output active, to generate the second and third output actives.</p> |
