Abstract

IN A THREE-PHASE POWER CONVERSION DEVICE THAT DRIVES A DC MOTOR (3) HAVING A FIELD MAGNET COIL (4) , SEMICONDUCTOR SWITHCHING ELEMENTS HAVING A THREE-PHASE CONVERSATION FUNCTION AND SMOOTHING CAPACITORS (14a1), (14a2) ARE RESPECTIVELY CONNECTED IN SERIES BETWEEN P AND N BUSES TO WHICH DC VOLTAGE IS APPLIED.OF THESE, THE DC MOTOR IS OPERATED BY THE CHOPPER ACTION OF AN ARMATURE CHOPPER DEVICE (13a) CONSTITUTED BY SEMICONDUCTOR SWITCHING ELEMENTS HAVING A TWO-PHASE POWER CONVERSATION FUNCTION.A FEEDBACK CIRCUIT ELEMENT (14d) IS CONNECTED WITH A FIELD MAGNET COIL BETWEEN THE FIELD MAGNET CHOOPER DEVICE (13b) CONSTITUTED BY SEMICONDUCTOR SWITCHING ELEMENTS HAVING A POWER CONVERSION FUNCTION OF THE REMAINING SINGLE PHASE ,AND THE MID-POINT (14c) OF THE SMOOTHING CAPACITORS.THE VOLTAGE OF THE MID-POINT IS PASSED TO THE FIELD MAGNET COIL BY THE CHOPPER ACTION BY THE FIELD MAGNET CHOPPER DEVICE AND THE ENERGY ACCUMULATED ON THE FIELD MAGNET COIL IS THREBY RETUNED TO THE MID-POINT OF THE FEEDBACK CIRCUIT ELEMENT.
