Electric power supplier, method for controlling supplying of electric power, and information processing device
First Claim
1. An electric power supplier comprising:
- an alternating/direct-current conversion circuit which converts an alternating voltage into a direct voltage, and outputs a converted voltage;
a first path, one end of which is connected to said alternating/direct-current conversion circuit, and other end of which is connected to a first load, said first path supplying output voltage of said alternating/direct-current conversion circuit to said first load;
a second path, one end of which is connected to said first path, and other end of which is connected to a second load, said second path supplying output voltage of said alternating/direct-current conversion circuit to said second load;
a switch circuit which is formed in said second path; and
a current detection circuit which detects a value of a current flowing a portion of said first path between said alternating/direct current conversion circuit and a node between said first path and said second path, and controls said switch circuit to electrically connect or disconnect the node to or from said second load, based on a detected current value.

Abstract
An electric power supplier includes an alternating/direct current conversion circuit, a first path, a second path, a switch circuit, and a current detection circuit. The alternating/direct current conversion circuit converts an alternating voltage to a direct voltage. One end of the first path is connected to a first load. One end of the second path is connected to the first path, and the other end thereof is connected to a second load. The first and second paths supply output voltage of the alternating/direct current conversion circuit to the first and second loads. The current detection circuit detects a value of the output current flowing through a node between the first and second paths, and controls the switch circuit, formed in the second path, to electrically connect or disconnect the node to/from the second load, based on a detected current value.
