Electrical inverter system

Claim 1

AN INVERTER SYSTEM COMPRISING: A SOURCE OF D.C. CURRENT; A TRANSFORMER HAVING AN OUTPUT WINDING, A FIRST INPUT WINDING, AND A SECOND INPUT WINDING; A VARIABLE IMPEDANCE CIRCUIT; A FIRST DISABLING TRANSFORMER HAVING A PRIMARY AND A SECONDARY WINDING; A SECOND DISABLING TRANSFORMER HAVING A PRIMARY AND A SECONDARY WINDING; A FIRST SWITCHING ELEMENT COMPRISING A FIRST CONTROLLED RECTIFIER; SAID D.C. SOURCE, SAID FIRST INPUT WINDING, SAID SECONDARY WINDING OF SAID FIRST DISABLING TRANSFORMER, SAID FIRST SWITCHING ELEMENT, SAID VARIABLE IMPEDANCE CIRCUIT, AND SAID PRIMARY WINDING OF SAID SECOND DISABLING TRANSFORMER DEFINING A FIRST SWITCHED CIRCUIT; A SECOND SWITCHING ELEMENT COMPRISING A SECOND CONTROLLED RECTIFIER; SAID D.C. SOURCE, SAID SECOND INPUT WINDING, SAID SECONDARY WINDING OF SAID SECONDARY DISABLING TRANSFORMER, SAID SECOND SWITCHING ELEMENT, SAID VARIABLE IMPEDANCE CIRCUIT, AND SAID PRIMARY WINDING OF SAID FIRST DISABLING TRANSFORMER DEFINING A SECOND SWITCHED CIRCUIT; MEANS FOR GENERATING CONTROL SIGNALS; AND MEANS FOR CAUSING SAID CONTROL SIGNALS TO ALTERNATELY ACTUATE SAID FIRST AND SAID SECOND SWITCHING ELEMENTS WHEREBY THE ACTUATED ONE OF SAID SWITCHING ELEMENTS ACTUATES ITS ASSOCIATED SWITCHED CIRCUIT THEREBY DISABLING THE UNACTUATED SWITCHING ELEMENT AND PRODUCTING AN OUTPUT SIGNAL.
