ELECTRICAL POWER SUPPLY APPARATUS AND CONTROLLING METHOD THEREOF
First Claim
1. An electrical power supply apparatus, comprising:
- a switch circuit;
an output circuit, connected to an external power source, for outputting a supply of main power source;
a standby circuit, connected to the external power source and the output circuit, for providing a supply of standby power source;
a single-direction pass circuit, connected to the external power source, the output circuit and the standby circuit; and
a control circuit, connected to the external power source, the control circuit controlling a conduction state of the switch circuit according to a state of the external power source,wherein when the external power source is on, the switch circuit is in a cutoff state for allowing a first period or a second period of a power signal of the external power source transferred to the standby circuit through the single-direction pass circuit.

Abstract
Disclosed is an electrical power supply apparatus, comprising a switch circuit, an output circuit, single-direction pass circuit and a control circuit. The output circuit is used for outputting a supply of main power source. The standby circuit is used for providing a supply of standby power source. The control circuit is for being capable of controlling the switch circuit according to a state of the external power source, wherein when the external power source is on, the switch circuit is in a cutoff state for allowing a first period or a second period of a power signal of the external power source transferred to the standby circuit through the single-direction pass circuit.
