Abstract
A voltage rectifying and smoothing circuit for use in a regulated power supply circuit which converts an ac voltage to a constant dc voltage. A voltage control circuit, which prevents the production of a voltage higher than a predetermined voltage, is connected to a rectifier circuit which rectifies an input ac current to convert it to a rectified voltage. The voltage smoothing circuit is connected on the output side of the voltage control circuit.
