Abstract
Electrical equipment includes a switching power source, a rectifier circuit, a pair of capacitative elements, and a load. The switching power source outputs an alternating-current voltage with input of a direct-current or an alternating-current power source voltage. The pair of capacitative elements are connected between the switching power source and the rectifier circuit and insulate the switching power source and the rectifier circuit. The load is connected as a load circuit to an output of the rectifier circuit and driven by a constant current.
