ABSTRACT:
A multi-phase DC-to-AC voltage boosting converter suitable for use as the primary stage of power isolated, high output voltage DC-to-DC voltage converters. The converter is comprised of a plurality of transformer primary windings electrically interconnected in a single loop mesh configuration and a plurality of voltage boosting channels operatively associated with the respective primary windings and commonly connected to a low voltage power source. The phase channels are operated so as to periodically provide a boosted voltage potential to the primary windings in a continuously cycling, multi-phase synchronous relation to one another so that a corresponding multi-phase, high-voltage AC potential is provided across each of said primary windings. Various conventional AC-to-DC converters and voltage multiplier circuits may be inductively coupled to the transformer primary windings to provide a wide variety of highly efficient low-to-high voltage DC-to-DC boost converters.
