Abstract:
A power supply device including a first power supply, a second power supply, a voltage control unit (VCU) stepping up a voltage from an input terminal to an output terminal, and an electronic control unit (ECU) is provided. The VCU includes an upper arm, a lower arm, a reactor having one end connected to the input terminal and the other end connected to a connection midpoint between the upper arm and the lower arm, and a current sensor acquiring a value of a current flowing in the reactor. At startup of the VCU, after performing a startup control that gradually increases a duty ratio of a transistor of the lower arm while turning off a transistor of the upper arm, the ECU performs a normal control that complementarily drives the transistors. During the startup control, the ECU determines whether to terminate the startup control using the acquired current value.

Claim (Index 1):
A power supply system, comprising:\n a first power supply; a second power supply; a voltage converter having an input terminal connected to the first power supply and an output terminal connected to the second power supply, the voltage converter stepping up and outputting a voltage from the input terminal to the output terminal; and a control device controlling the voltage converter, wherein the voltage converter comprises:\n an upper arm comprising a switching element having one end connected to a positive electrode of the output terminal; \n a lower arm comprising a switching element having one end connected to the upper arm and the other end connected to a negative electrode of the output terminal; \n a reactor having one end connected to a positive electrode of the input terminal and the other end connected to a connection midpoint between the upper arm and the lower arm; and \n a reactor current acquisition part acquiring a value of a current flowing in the reactor; \n at startup of the voltage converter, the control device performs a startup control that gradually increases a duty ratio of the switching element of the lower arm in a state in which the switching element of the upper arm is turned off, then performs a normal control that complementarily drives the switching element of the upper arm and the switching element of the lower arm, and during execution of the startup control, determines whether to terminate or to continue with the startup control by using the value of the current acquired by the reactor current acquisition part.
