Title:
CONTROL DEVICE FOR ELECTRIC DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024244
Kind Code:
A1
Abstract:
A connector unit (11) has at least: a first power supply connector (12a) having a first ground side terminal (12a(-)) used for power supply to a first drive system; and a second power supply connector (12b) having a second ground side terminal (12b(-)) used for power supply to a second drive system. The connector unit (11) is also formed with a common ground (31) to which the mutual ground wirings of a first control circuit unit (30a) and a second control circuit unit (30b) are connected and a resistor (43), thereby enabling to suppress the increase in the wiring distance to the common ground (31) and enabling to suppress the variation of the ground voltage level due to the increase of a wiring impedance.
