VOLTAGE CONVERTING DEVICE

Abstract:

A voltage converting device includes: a DC/DC converter configured to step down a voltage of a power supply and output the stepped-down voltage to a low-voltage power supply having a voltage lower than a voltage of the power supply; a control device configured to control the DC/DC converter; and a determining unit configured to determine whether a voltage of the power supply input to the DC/DC converter is within a predetermined voltage range, wherein the control device switches, on the basis of a determination result of the determining unit, between a first control in which the DC/DC converter is caused to perform a step-down operation and electric power is supplied to a load connected to the low-voltage power supply and a second control in which a step-down operation of the DC/DC converter stops and electric power is supplied from the low-voltage power supply to the load.
