Title:
CONTROL DEVICE FOR ELECTRIC DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024245
Kind Code:
A1
Abstract:
A circuit board (100) is disposed so as to be formed with a heat dissipation path at at least a part thereof, and a common ground (31) is electrically connected to a first drive circuit (33a) and a second drive circuit (33b) respectively on the circuit board (100) via resistance bodies (R1). The resistance bodies (R1) that flow through power supply connectors (12) via a common ground line are mounted on the circuit board (100), thereby enabling to suppress the increase in temperature by dissipating heat from the heat dissipation path of the circuit board (100) even if relatively large current flows during failure and heat generation occurs.
