To provide charging equipment which operates a switch stably at load ripple and suppresses a rush current flowing to a smoothing capacitor at recovery from instantaneous power failure and shortens the recovery time at instantaneous power failure.

The charging equipment 80 is composed of a three-phase power source 1, rectifying elements 2-7, a current limiting resistor 9, a smoothing capacitor 8, a switch 10, an instantaneous power failure signal generator 55, a reference voltage value setter 56, a first comparator 54, a first control circuit 70, and a second control circuit 71. The first control circuit logically operates an instant stop signal, an output signal of the first comparator, and an output signal of the second comparator, and it sets or resets a holding circuit by the operation results, and controls the ON-OFF of the switch by the output of the holding circuit.
