Abstract: In one embodiment, a DC/DC converter includes: a first switching element, a diode connected to the first switching element, an inductor connected to at least one of the first switching element and the diode, and a circuit connected in parallel to the first switching element, the circuit including a second switching element. A current flowing through the circuit when the second switching element is on is smaller than the current flowing through the first switching element when the first switching element is on, and the second switching element is turned on a lead time before the timing at which the first switching element is turned on.

Abstract: A medical image diagnosis apparatus includes a power factor corrector, a DC/DC converter, and a battery device. The power factor corrector is supplied with AC power and generates DC power to drive individual parts of the apparatus. The DC/DC converter converts the voltage of the DC power generated by the power factor corrector to a voltage desired for driving the individual parts. The battery device includes a battery that stores DC power, a discharging circuit that is connected to the downstream side of the power factor corrector and supplies the DC power from the battery to the individual parts, and a charging circuit that is connected to the upstream side of the power factor corrector, and is supplied with AC power and supplies DC power to the battery. The battery device supplies the DC power to the individual parts when the power factor corrector cannot supply the DC power.
