摘要: A power conversion device according to an aspect of an embodiment includes a power conversion unit and a control unit. The power conversion unit includes N (N is an integer number not less than two) power converters that output voltages on the basis of base signals having the same period and phase differences equivalent to ½N of the period of the base signal. The control unit controls the N power converters by using ½ of the period of the base signal as a control period and shifts each of control timings of the N power converters by the ½N of the period of the base signal.

摘要: A series multiplex power conversion apparatus includes a plurality of phases. Each of the plurality of phases includes a plurality of power conversion cells coupled in series to each other. Each of the plurality of power conversion cells includes a current detector configured to detect a current through one phase among the plurality of phases corresponding to the current detector. Each of the plurality of power conversion cells is configured to independently stop a power conversion operation based on the current detected by the current detector.
