DC/DC CONVERSION DEVICE AND LOAD DRIVE CONTROL SYSTEM |
摘要 |
A DC/DC conversion device that includes three-level power conversion circuits in a plurality of phases. The DC/DC conversion device includes voltage detectors 21 and 22 that detect at least two voltages (Efc and EfcL) of an input DC voltage, a first divided voltage, and a second divided voltage; and a voltage control unit 3 that controls an output voltage of three-level power conversion circuits 12a and 12b. At least one phase (the power conversion circuit 12b) of the three-level power conversion circuits 12a and 12b operates as an imbalance-reduction phase that executes imbalance-reduction control such that one (EfcL) of the first and second divided voltages is divided into half of the input DC voltage Efc. |
