Static inverter system

Claim 1

AN INVERTER SYSTEM COMPRISING: A SOURCE OF DIRECT CURRENT POWER; A REGULATOR CIRCUIT CONNECTED TO SAID SOURCE OF DIRECT CURRENT POWER FOR OBTAINING A REGULATED DIRECT VOLTAGE OUTPUT; SENSING MEANS INCLUDING A SATURABLE CORE TRANSFORMER CONNECTED TO SENSE AN EXCESSIVE CURRENT CONDITION IN A POWER LEAD FROM SAID SOURCE OF DIRECT CURRENT POWER, TO PRODUCE AN OUTPUT SIGNAL WHEN THE EXCESIVE CURRENT CONDITION IS SENSED; CONTROL MEANS FOR CONTROLLING THE REGULATED DIRECTED VOLTAGE OUTPUT OF SAID REGULATOR CIRCUIT, SAID CONTROL MEANS BEING RESPONSIVE TO THE OUTPUT SIGNAL OF SAID SENSING MEANS FOR CAUSING THE REMOVAL OF THE REGULATED DIRECT VOLTAGE OUTPUT FROM SAID REGULATOR CIRCUIT FOR A PREDETERMINED DURATION; A SEQUENTIAL PULSE GENERATOR INCLUDING A SATURABLE, MULTIPLE CORE TRANSFORMER HAVING PRIMARY AND FEEDBACK WINDINGS AROUND ALL THE CORES, SERIES CONNECTED BIAS WINDINGS OF SUCCESSIVELY INCREASING AMPERE-TURNS ON EACH OF CERTAIN CORES AND AN OUTPUT WINDING FOR EACH CORE, AND A PAIR OF TRANSISTORS CONNECTING WITH SAID PRIMARY AND FEEDBACK WINDINGS IN A MULTIVIBRATOR CIRCUIT; THREE PAIRS OF DRIVER TRANSISTORS; MEANS CONNECTING THE OUTPUT WINDINGS OF SAID PULSE GENERATOR TO RESPECTIVE PAIRS OF SAID DRIVER TRANSISTORS TO APPLY THE SEQUENTIAL SIGNALS FROM SAID PULSE GENERATOR IN THREE PHASES OF OUTPUT SIGNALS THERETO, TO CONTROL CONDUCTION OF SAID DRIVER TRANSISTORS IN A THREE PHASE SEQUENCE; THREE TRANSFORMERS EACH HAVING A CENTER TAPPED PRIMARY WINDING AND DOUBLE SECONDARY WINDINGS, SAID PRIMARY WINDINGS OF SAID TRANSFORMERS BEING CONNECTED TO RESPECTIVE PAIRS OF SAID DRIVER TRANSISTORS, AND SAID CENTER TAPS AND COMMON JUNCTION BETWEEN EACH OF SAID PAIRS OF DRIVER TRANSISTORS BEING CONNECTED TO THE REGULATED DIRECT VOLTAGE OUTPUT OF SAID REGULATOR CIRCUIT; AND THREE PAIRS OF POWER TRANSISTORS ADAPTED TO BE SUPPLIED BY SAID SOURCE OF DIRECT CURRENT POWER, SAID POWER TRANSISTORS OF EACH PAIR BEING RESPECTIVELY CONNECTED TO SAID DOUBLE SECONDARY WINDINGS OF A CORRESPONDING ONE OF SAID THREE TRANSFORMERS AND ARE COMPLEMENTARY CONDUCTIVE AND NON-CONDUCTIVE IN RESPONSE TO A CORRESPONDING PHASE OF THREE PHASES OF OUTPUT SIGNALS, FOR CONTROLLING THE DIRECT CURRENT OUTPUT POWER FROM SAID SOURCE APPLIED TO SAID POWER TRANSISTORS TO PRODUCE OUTPUT POWER TO A LOAD IN ACCORDANCE WITH VARIATIONS OF THE THREE PHASE SEQUENCE.
