PROBLEM TO BE SOLVED: To provide capacitor charging equipment whose output voltage can be accurately detected in simple circuit constitution. SOLUTION: The capacitor charging equipment 210 comprises: a transformer 10; and an output capacitor C1 which is charged with a current that flows in the secondary coil 14 of the transformer 10, and charges the output capacitor C1 by controlling the switching of a switching transistor Tr1 provided on the path of the primary coil 12 of the transformer 10. The switching controller 40 controls the ON-OFF of the switching transistor Tr1. A voltage detectors (18 and 108) monitor the voltage Vmoni of a tap 16 provided in the secondary coil 14 of the transformer 10. The switching controller 40 controls the ON-OFF of the switching transistor Tr1, regarding the voltage Vmoni detected by the voltage detector as the output voltage Vout of capacitor charging equipment 210.
