VOLTAGE CONVERSION DEVICE, MOTOR DRIVE DEVICE, AND METHOD OF CONTROLLING VOLTAGE CONVERTER

摘要

When prescribed abnormality occurs, a control unit suspends a boost converter (S20). When an abnormal state is eliminated (YES at S40), the control unit checks whether or not a voltage VH of a high-voltage side (an inverter side) of the boost converter is lower than a withstand voltage of a part of equipment connected to a low-voltage side (a battery side) of the boost converter (S60). The control unit stops issuance of an instruction to suspend the boost converter after voltage VH becomes lower than the withstand voltage of the part (S70).
