Medical image diagnosis apparatus

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.
