Abstract
A power supply circuit including a first rectifying smoother for generating a DC output when connected to an AC power source. A standby power source that provides a plurality of DC outputs when supplied with the DC output from the first rectifying smoother. A second rectifying smoother converts the AC input into a DC output, which is converted by the main power source into a desired DC voltage. On the primary side of the main and standby power source, a relay controller, supplied with power by one of the DC outputs from the standby power source, responds to an actuation of a main switch. A relay switch connects the AC power source to the second rectifying smoother upon actuation of the relay controller. The standby power source also supplies power to the control means, which is disposed on the secondary side of the main and standby power source.
