Power conversion device

Abstract

A power conversion device according to an embodiment of the present invention comprises: a 1-1 input/output unit and a 1-2 input/output unit respectively connected to a first high voltage side and a second high voltage side connected in series; a first power conversion unit connected to the 1-1 input/output unit; a second power conversion unit connected to the 1-2 input/output unit; a second input/output unit connected to the first power conversion unit and the second power conversion unit and connected to a low voltage side; and a control unit that controls the operation of the first power conversion unit or the second power conversion unit, wherein the control unit controls to convert the voltages of the first high voltage side and the second high voltage side, and output the converted voltage to the low voltage side, or convert the voltage of the low voltage side, and output the converted voltage to the first high voltage side or the second high voltage side, and operates bidirectionally.
