<p>PROBLEM TO BE SOLVED: To provide a power conversion device capable of mitigating conditions to restrict magnitude relations of voltage among ports.SOLUTION: A power conversion device has a primary circuit and a secondary circuit which is magnetically coupled with the primary circuit using a transformer. The primary circuit or the secondary circuit has a first port, a second port, a first voltage section, a second voltage section, a voltage conversion section which converts voltage between the first voltage section and the second voltage section, and a switching section for switching a connection state among the first port, the second port, and the voltage conversion section between a first state in which the first port and the first voltage section are connected with each other and the second port and the second voltage section are connected with each other and a second state in which the first port and the second voltage section are connected with each other and the second port and the first voltage section are connected with each other.</p> |
