Abstract
PURPOSE: To reduce size by regenerating electromagneticen ergy to the AC power source side even at the time of power running and also at the time of brake running.
CONSTITUTION: Rectifying power source "off" diodes 45 to 50 are connected between the power supply side terminals of an inverter comprising GTRs 7 and 8, thyristors 1 to 6 and diodes, and regeneration inverter thyristors 65 to 70 are connected in opposite porality parallel connection. As a control circuit, a braking commutation control circuit 54, a power source phase detection circuit 56 and an angle γ setting delay circuit 7 are provided separately of the conventional control circuit. Thus, electromagnetic energy of the motor is reliably regenerated to the power source at the time of the power running, and electromagnetic energy of the motor and regenerative energy at the time of the brake running, so that stable regenerative braking can be obtained. Also, size reduction can be obtained by reducing the capacitance of a buffer capacitor 13.
