Title:
POWER SOURCE DEVICE AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/062681
Kind Code:
A1
Abstract:
This power source device comprises a DC power source (13), inverters (42A, 42B) to which power is supplied from the DC power source, capacitors (CA1, CA2, CB1, CB2) connected in parallel to the inverters between the DC power source and the inverters, reverse connection protection circuits (44A, 44B) connected between the DC power source and the capacitors to block a flow of current from the capacitors to the DC power source through a positive electrode side power source line (Lpa) of the DC power source, and overvoltage protection circuits (45A, 45B) that each control a voltage between both ends of a capacitor such that the voltage becomes equal to or smaller than a predetermined voltage if the voltage becomes equal to or larger than the predetermined voltage.
