Title:
POWER CONVERSION DEVICE AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/024425
Kind Code:
A1
Abstract:
This power conversion device comprises: a high-potential-side electrical path (22H); a low-potential-side electrical path (22L); an inverter (20) having upper arm switches (SWH) and lower arm switches (SWL); and a motor (10) having armature windings (11) that are electrically connected, via conductive members (23), to connection points of the upper and lower arm switches. The power conversion device comprises: an inter-power-storage-unit switch (40) that is provided to an inter-power-storage-unit electrical path (24) that electrically connects a negative terminal of a first power storage unit (31) and a positive terminal of a second power storage unit (32); a bypass switch (50, 51) that makes an electrical connection between the negative terminals of the first and second power storage units and/or an electrical connection between the positive terminals of the first and second power storage units; and motor-side electrical paths (25–28) that electrically connect the armature windings or the conductive members to the inter-power-storage-unit electrical path.
