Improved multiple core transformer inverter with TRC regulation via external variable volt-second saturable reactor

Design of a polyfunction inversion device is described together with pertinent equations required for its development. The low-voltage converter under consideration was developed with switching drive power proportional to load current, utilizing multiple core techniques. Driven power transistors were used to rectify the output of the inverter-regulator to maintain system efficiency. Regulation was provided by using variable volt-second techniques which were external to the power transformer, permitting the power transformer to be fabricated from semi-square low-loss core material.
