Provided is a boost converter control device capable of reducing total loss. In a power supply system provided with a direct current power supply having a power-supply voltage (VB), a boost converter that is provided with a switching means and that outputs to a load device after boosting the power-supply voltage (VB) using a prescribed boost control that includes switching the switching state of the switching means on the basis of a boost command voltage, and a voltage detection means that detects the output voltage (VH) of the boost converter, a boost converter control device (100) that controls the boost converter has a boost control means that executes the boost control and an intermittent control means that executes intermittent processing of the boost control based on the detected output voltage (VH) so as to maintain the output voltage (VH) within a range that includes the boost command voltage at the time of execution of the immediately preceding boost control.
