Abstract

PURPOSE:To reduce the number of component parts and lower a cost, by using fly-wheel diodes, and diodes connected to a motor output terminal, at the time of stopping a motor, and by permitting braking current to flow. CONSTITUTION:Three-phase AC input is rectified by a bridge circuit 5 and is fed to an inverter 1, and AC output from the inverter 1 is fed to a motor. When power transistors 61-66 at the inverter 1 in case of stopping the motor are all turned OFF, then via fly-wheel diodes 72, 74, 76 connected to the negative side of a DC circuit and diodes 81-53 connected to a motor output terminal, a braking switch 10, and a power generation braking resistor 9, braking current based on a motor counter-electromotive-force flows.
