Phase current balancing for multiphase rectifier circuits

Claim 1

A PHASE CURRENT BALANCING CIRCUIT FOR MULTI-PHASE SYSTEMS; SAID PHASE CURRENT BALANCING CIRCUIT INCLUDING RESPECTIVE REACTOR CORES FOR EACH OF SAID PHASES; EACH OF SAID REACTOR CORES HAVING A MAIN WINDING CONNECTED IN SERIES WITH ITS SAID RESPECTIVE PHASE; EACH OF SAID REACTOR CORES HAVING A BIASING WINDING AND AN INDEPENDENT SOURCE OF BIASING CURRENT CONNECTED TO EACH SAID BIASING WINDING; SAID SOURCE OF BIASING CURRENT FOR EACH OF SAID PHASES BEING CONNECTED TO THE OTHER OF SAID PHASES WHICH CONDUCTS CURRENT BEFORE SAID PHASE ASSOCIATED WITH SAID SOURCE OF BIASING CURRENT; SAID SOURCE OF BIASING CURRENT BEING CONTROLLED TO REVERSE A CONTROLLED PORTION OF FLUX OF ITS SAID RESPECTIVE MAGNETIC CORE PRIOR TO ZERO PASSAGE OF CURRENT THROUGH THE SAID PHASE ASSOCIATED WITH SAID SOURCE OF BIASING CURRENT; THE REMAINDER OF SAID FLUX OF SAID MAGNETIC CORE BEING REVERSED UPON CHANGE OF CURRENT IN SAID PHASE FROM ZERO CURRENT TO PROVIDE A CONTROLLED TIME DELAY IN THE BEGINNING OF CURRENT FLOW FROM A ZERO VALUE; AND MEANS FOR ADJUSTING THE MAGNITUDE OF THE BIASING CURRENT FOR EACH PHASE INDEPENDENTLY OF ONE ANOTHER TO CONTROL THE AMOUNT OF FLUX REVERSED IN EACH RESPECTIVE CORE PRIOR TO CURRENT ZERO IN EACH RESPECTIVE PHASE; SAID MAGNETIC CORES HAVING A RELATIVELY LOW MAGNETIZING CURRENT; SAID SOURCES OF BIASING CURRENT BEING ELECTRICALLY CONNECTED TO THEIR SAID RESPECTIVE BIASING WINDINGS IN SERIES WITH A RESPECTIVE REACTOR HAVING AN ADJUSTABLE AIR GAP THEREIN.
