In case of decelerating a permanent magnet motor, an over-voltage occurs on the inverter DC voltage due to the regenerative energy of the motor. In order to reduce the over-voltage, a brake circuit is usually applied to the DC circuit.<br>In this paper a reduction technique of the over-voltage without the brake circuit is described. We proposed the method for controlling the motor d-axis current optimally according to the motor q-axis current to reduce the over-voltage. This method is applied to the salient-pole machine. As a result over-voltage reduction is achieved on a certain condition.
