<P>PROBLEM TO BE SOLVED: To provide a standby voltage setting circuit and a standby voltage setting method, a power supply, and a power supply control method for making a standby voltage equal to an output terminal voltage as a normal value, by removing a forward voltage of a clamp diode if a load circuit or another power supply operated in parallel is excessive in voltage, and to provide a power supply system for making the power supply automatically in a standby state at a normal value of the output terminal voltage if two or more power supplies are put in parallel connection. <P>SOLUTION: The standby voltage setting circuit includes a circuit for detecting a voltage on an anode side and a cathode side of an OR diode, a clamp diode, a voltage follower for generating a voltage obtained, by shifting a voltage almost equal to the forward voltage of the clamp diode, and an output voltage control circuit for comparing the voltage detected on the cathode side with a prescribed voltage and generating a result to the power supply circuit. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
