Title:
DYNAMO-ELECTRIC MACHINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/070824
Kind Code:
A1
Abstract:
A first inverter (36) drives a first dynamo-electric machine (37). A second inverter (46) drives a second dynamo-electric machine (47). A first control unit (33) controls the first inverter (36). A second control unit (43) controls the second inverter (46). A first power feed path (30) feeds power to the first control unit (33). A second power feed path (40) feeds power to the second control unit (43). A connection path (50) electrically connects the first power feed path (30) and the second power feed path (40) to each other. A ground fault determining unit (63) determines whether there is a ground fault element that indicates that a ground fault has occurred or indicates the possibility thereof in the first power feed path (30) or the second power feed path (40). Blocking units (54, 64) block the connection path (50) on the condition that it has been determined a prescribed ground fault element exists.
