Claims

[Scope of utility model registration request]

A rectifier circuit that converts an AC input into a DC output and supplies the DC output to a load includes a first two-terminal circuit consisting of a first capacitor with a small capacity, and a second circuit having a capacity larger than the first capacitor. A second two-terminal circuit formed by connecting the second capacitor and the actuator in series through a diode whose cand side is connected to the capacitor is connected in parallel to form a composite two-terminal circuit. A connection point between the first capacitor and the reactor is connected to a high potential side of a rectifier, a connection point between the first capacitor and the second capacitor is connected to a low potential side, and both ends of the second capacitor are connected to a DC output terminal. A rectifying device characterized by:
