<P>PROBLEM TO BE SOLVED: To provide a power supply circuit. <P>SOLUTION: The power supply circuit is used to supply electric power to a plurality of loads, and includes a control circuit with a plurality of control terminals, a first power supply circuit, a second power supply circuit, and a third power supply circuit. The power supply circuits are connected to one control terminal of the control circuit respectively and all have a switching unit, which includes a first terminal, a second terminal, and a switching terminal for controlling connection and disconnection between the first terminal and second terminal, the first terminal being connected to a power source, the second terminal being connected to one load, and the switching terminal being connected to the control terminal. The second power supply circuit and third power supply circuit all further include a delay circuit, which is connected between the control terminal of the control circuit and the switching terminal of the switching unit, and a delay time of a delay circuit of the third power supply circuit is longer than a delay time of a delay circuit of the second power supply circuit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
