Abstract

PURPOSE: To improve the operation efficiency through supply of charged load from a load motor by controlling the switch so that a closed loop is formed including a voltage generated by the load motor and a commutation capacitor in shifting the drive source of the motor to an inverter circuit from a separate power source such as commercial power source.
CONSTITUTION: In stead of a charging circuit of a commutation capacitor, a series circuit comprising a thyristor 211 opposite to the main thyristor and a current limiting impedance 212 between the DC power sources PN. With the simultaneous firing of a thyristor 171 on the phase R positive side, a thyristor 176 on the phase T negative side, and a thyristor 212, a closed loop is formed to charge commutation capacitors 194, 195 and 196. At this point, the charging energy to the commutation capacitor utilizes a voltage induced by a motor 13
