Abstract
In a remotely controlled power supply, a switching element has a main switching section coupled to an input voltage source and an on/off control section responsive to an on/off switching signal. A main power supply includes an input side which receives main power from the source when the main switching section is in the closed position and an output side for supplying power to loads. An on/off decoder decodes a command signal having a plurality of states including a run state and a standby state to provide the aforementioned on/off switching signal. A standby power supply is coupled to the input voltage source for providing standby power to the on/off decoder during standby, whereas the switching element disconnects the main power supply from the source during standby. A second decoder decodes the other states of the command signal. The two decoders may be provided with separate system clock generators that are operated asynchronously of each other.
