摘要： A DC-DC converter converts a DC input to a predetermined high-voltage DC output according to a predetermined control signal. An output unit has a pair of high- and low-voltage-side output paths and supplies the predetermined high-voltage DC output to a load. An output variation detecting unit has a resistor voltage dividing circuit including high- and low-voltage-side resistors connected in series between the pair of output paths and detects a variation in predetermined high-voltage DC output that follows a variation in the load. An inner shield shields the exterior of the resistor voltage dividing circuit. The inner shield is electrically connected to a node of the high- and-low voltage-side resistors. An outer shield shields the exterior of the inner shield. The outer shield is electrically connected to the low voltage-side output path of the pair of output paths. A control unit receives a voltage component generated across both ends of the low-voltage-side resistor of the resistor voltage dividing circuit, generates the predetermined control signal in accordance with the voltage component, and supplies the predetermined control signal to the DC-DC converter.
