POWER CONVERSION DEVICE AND PROGRAM

WIPO Patent Application WO/2024/053423

A1

This power conversion device comprises: an inverter (20); a motor (10) that has an armature winding (11); an inter-power-storage-unit switch (40) that is provided to an inter-power-storage-unit electrical path (24) which electrically connects a negative electrode terminal of a first power storage unit (31) and a positive electrode terminal of a second power storage unit (32); bypass switches (50, 51); motor-side electrical paths (25-28) that electrically connect the armature winding and the inter-power-storage-unit electrical path; and a control unit (100). When it is determined that there is a request for power transmission between the first power storage unit and the second power storage unit, the control unit controls transmission of power between the first power storage unit and the second power storage unit by switching of the inverter, with the operation mode of the inter-power-storage-unit switch and the bypass switch being set to a first mode for turning on the inter-power-storage-unit switch and turning off the bypass switch or a second mode for turning off the inter-power-storage-unit switch and turning on the bypass switch.
