Abstract
A CURRENT CHECK COMMAND (ICHK) TURNS ON IMMEDIATELY BEFORE A CAR (2) STARTS TO RUN, AN INVERTER (4) APPLIES A VOLTAGE FOR CAUSING A CURRENT FOR CONFIRMING AN OPEN PHASE TO FLOW THROUGH EACH OF PHASES OF A THREE-PHASE AC MOTOR (1) TO EACH OF THE PHASES. A CURRENT VALUE OF THE CURRENT THAT FLOWS THROUGH EACH OF THE PHASES IS DETECTED BY CURRENT DETECTORS (10A, 10B) AND COMPARED WITH A REFERENCE VALUE PRESET FOR DETERMINING AN OPEN PHASE. WHEN THE DETECTED CURRENT VALUE IS LOWER THAN THE REFERENCE VALUE, IT IS DETERMINED THAT THE THREE-PHASE AC MOTOR (1) IS IN OPEN PHASE, AND THE CAR (2) IS INHIBITED FROM STARTING TO RUN AT ONCE.
