Power converter circuit operating as an electric potential transformer

Abstract

Abstract A POWER CONVERTER CIRCUIT OF ELECTRONIC TRANSFORMER FOR AN A.-C. SUPPLY COMPRISES A LINEAR TRANSFORMER WHOSE WINDINGS ARE CONNECTED RESPECTIVELY TO INPUT AND OUTPUT TERMINALS THROUGH INVERTER CONFIGURATION SWITCHING CIRCUITS EMPLOYING BIDIRECTIONAL CONDUCTING SOLID STATE SWITCHING DEVICES OR INVERSE-PARALLEL PAIRS OF UNIDIRECTIONAL CONDUCTION SOLID STATE SWITCHING DEVICES. BY SYNCHRONOUSLY RENDERING CONDUCTIVE ONE SWITCHING DEVICE IN THE PRIMARY AND SECONDARY SIDE SWITCHING CIRCUITS, AND ALTERNATELY AND SYNCHRONOUSLY RENDERING CONDUCTIVE ANOTHER DEVICE IN EACH CIRCUIT AT A SWITCHING RATE SUBSTANTIALLY HIGHER THAN THE SUPPLY FREQUENCY, THE INPUT POTENTIAL IS CONVERTED TO A HIGHER FREQUENCY WAVE, TRANSFORMED, AND RECONSTRUCTED AT THE OUTPUT TERMINALS. IN THIS WAY THE SIZE OF THE TRANSFORMER IS REDUCED.
