<p>PROBLEM TO BE SOLVED: To provide a power conversion device capable of outputting minute voltage while suppressing a switching loss in an inverter section.SOLUTION: A power conversion device according to an embodiment comprises an inverter section and a PWM control section. The inverter section includes bridge-connected four switching elements. The PWM control section makes the inverter section output AC voltage by changing over and executing a first control mode for performing on/off control of two switching elements out of the four switching elements and stopping on/off of the remaining switching elements and a second control mode for alternately performing on/off control of the four switching elements in unit of two switching elements.</p> |
