Abstract
A DC/DC conversion device that includes three-level power conversion circuits in a plurality of phases. The DC/DC conversion device includes voltage detectorsandthat 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 unitthat controls an output voltage of three-level power conversion circuitsand. At least one phase (the power conversion circuit) of the three-level power conversion circuitsandoperates 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.
