Abstract:
Provided is a DC/DC converter that suppresses an inrush current flowing into a capacitor. A DC/DC converter (1) comprises: a first capacitor (C1) and a second capacitor (C2) respectively provided between a reference conductive path (93) and one conductive path among a first conductive path (91) and a second conductive path (92); a first cutoff switch (71) and a second cutoff switch (72) interposed between a first external power supply (61) and the first capacitor (C1) and between a second external power supply (62) and the second capacitor (C2); and a control unit (12) for switching the first cutoff switch (71) and the second cutoff switch (72) between an on state and an off state, wherein when switching from cutoff control for maintaining the first cutoff switch (71) and the second cutoff switch (72) in an off state to power supply control for maintaining the first cutoff switch (71) and the second cutoff switch (72) in an on state, the control unit (12) performs intermittent control for intermittently setting the first cutoff switch (71) and the second cutoff switch (72) to an on state before the power supply control.
