Title:
CONTROL DEVICE FOR POWER CONVERTER AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/009686
Kind Code:
A1
Abstract:
A control device (60) is applied to a system comprising: a power storage unit (10, 100, 200); a plurality of power converters (20, 40, 70, 80, 110, 210); a rotary electric machine (30, 90, 120, 220) that has windings electrically connected to the power converters; and a heat transfer unit (400, 401) that transfers the heat generated in at least one of the power converters to an element to be heated (10, 100, 200). The control device comprises: a determination unit that determines whether there is a need to heat the element to be heated; and a control unit that, when the determination unit determines that there is a need to heat the element to be heated, performs power converter switching control whereby a rotation stopped state of a rotor (31, 91, 121, 221) of the rotary electric machine is maintained while alternating d/q axis currents are supplied to the windings (32, 34U-34W, 93A, 93B, 123U-123W, 223U-223W).
