Abstract
Apparatus for supplying from a single-phase, known-frequency AC source, three-phase AC power at the same frequency. The apparatus features circuitry which employs high-speed power switching with respect to only one phase of a three-phase load, with the result that only two high-speed power-switching devices (transistors) are required.
