Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/153313
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power conversion device capable of reducing noise that occurs when increasing the temperature of a storage battery is controlled. This power conversion device (10) is provided with: a rotary electric machine (40) having windings (41U, 41V, 41W, 41X, 41Y); an inverter (30) having a serial connector of upper arm switches (QUH, QVH, QWH, QXH, QYH) and lower arm switches (QUL, QVL, QWL, QXL, QYL); and a capacitor (31) connected in parallel to the serial connector. The power conversion device is further provided with: connection paths (60, 90, 90U, 90W) which, in a first storage battery (21) and a second storage battery (22) connected in series, electrically connect the windings and the negative electrode side of the first storage battery and the positive electrode side of the second storage battery; and a control unit (70) which controls switching of the upper arm switches and the lower arm switches such that current flows between the first storage battery and the second storage battery via the inverter, the windings, and the connection paths.
