PURPOSE:To enable the effective charge of a battery with the power at the time of generation mode by equipping it with a brake current fixing means, a step-up means for the terminal voltage of a capacitor for smoothing, and a generalized control arithmetic unit for a chopping transistor. CONSTITUTION:Only the induced electromotive force is applied only in the motor winding connected in three-phase Y at the same time when the driver of a power regenerator 36 gets in generation mode, and the feedback diodes 15-60 of an inverter part work as full bridge full wave rectification, and a smoothing capacitor 8 smooths the full wave rectification output voltage so as to average the pulsating currents. On the other hand, average treatment is performed after the acceleration aperture zero judgment of a charge current fixing/current rationalization control block 33 and the detection of the interline voltage with a Hall element type current detection sensor 32, and a generation mode judging block 34 monitors the current value and the direction so as to judge the change from the operation state to generation state. And, if one chops the transistor 30 for chopping immediately, the terminal voltage of the smoothing capacitor 8 is boosted by a coil 7. |
