Controlled rectifier circuit

Claim 1

A RECTIFIER CONTROLLABLE FOR ENERGIZING AND DEENERGIZING A LOAD DEVICE COMPRISING A SOURCE OF ELECTRICAL PULSES, FIRST AND SECOND BRANCH CIRCUITS COUPLED TO SAID SOURCE AND SAID LOAD DEVICE, A UNIDIRECTIONAL DEVICE IN EACH BRANCH CIRCUIT RESPONSIVE TO PULSES OF PREDETERMINED POLARITY TO ENERGIZE SAID BRANCH CIRCUITS ALTERNATIVELY, A SATURABLE TRANSFORMER INCLUDING A FIRST PRIMARY WINDING IN SAID FIRST BRANCH CIRCUIT AND A SECOND PRIMARY WINDING IN SAID SECOND BRANCH CIRCUIT, SAID WINDINGS BEING WOUND ON OPPOSITE LEGS OF A COMMON CORE, A SEMI-CONDUCTOR DEVICE IN EACH BRANCH CIRCUIT AND INCLUDING A COLLECTOR COUPLED TO ONE OF SAID PRIMARIES, AN EMITTER COUPLED TO SAID LOAD DEVICE, AND A BASE WHEREBY A CERTAIN NORMAL POTENTIAL IS ESTABLISHED ON SAID COLLECTOR AND EMITTER, SAID SATURABLE TRANSFORMER INCLUDING A FIRST SECONDARY WINDING ASSOCIATED WITH THE PRIMARY WINDING OF SAID FIRST BRANCH CIRCUIT AND COUPLED TO THE BASE OF THE SEMI-CONDUCTOR DEVICE THEREIN AND ALSO INCLUDING A SECOND SECONDARY WINDING ASSOCIATED WITH THE PRIMARY WINDING OF SAID SECOND BRANCH CIRCUIT AND COUPLED TO THE BASE OF THE SEMI-CONDUCTOR DEVICE THEREIN, EACH OF SAID SECONDARY WINDINGS HAVING A TAP POINT THEREIN, A SOURCE OF CONTROL SIGNALS OF DIFFERENT POLARITIES, AND MEANS COUPLED BETWEEN SAID CONTROL SIGNAL SOURCE AND SAID SECONDARY FOR COUPLING SAID SOURCE OF CONTROL SIGNALS IN OPPOSITE POLARITY TO EITHER OF SAID SECONDARY WINDINGS TO CHANGE THE BIAS ON SAID SEMI-CONDUCTOR DEVICES TO INITIATE FLOW OF POWER FROM SAID PULSE SOURCE TO SAID LOAD DEVICE, SAID SATURABLE TRANSFORMER MAINTAINING FLOW OF POWER BY INDUCTION, AND A UNIDIRECTIONAL DEVICE COUPLED BETWEEN THE TAP POINT OF EACH OF SAID SECONDARY WINDINGS AND THE EMITTER OF THE SEMI-CONDUCTOR DEVICE TO THE BASE OF WHICH THE SECONDARY WINDING IS COUPLED, TO AVOID PRODUCTION OF CURRENT THROUGH SAID CONTROL SOURCE IN RESPONSE TO THE FLOW OF POWER TO SAID LOAD DEVICE.
