Title:
DRIVING CONTROL DEVICE, DRIVING DEVICE, AND POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066182
Kind Code:
A1
Abstract:
One embodiment of this driving control device comprises: an inverter that supplies power to a motor through an on/off action of a switching element; a smoothing capacitor; and a control unit, wherein when the temperature of the smoothing capacitor or the temperature of the surroundings of the smoothing capacitor is a first temperature, the control unit allows a circulating current from the motor to flow to the smoothing capacitor via the switching element, which is in an on condition, and when the temperature of the smoothing capacitor or the temperature of the surroundings of the smoothing capacitor is a second temperature that is lower than the first temperature, the control unit allows the circulating current from the motor to flow to the smoothing capacitor via a parasitic diode of the switching element.
