Abstract

The invention discloses a power supply system, a linear control module and a switch element control method. The linear control module is electrically connected to a power supply device. The power supply device comprises an AC / DC power supply converting module, a switch element, a control signal output end, a main power supply output end and a standby power supply output end. The AC / DC power supply converting module has an electric power output end. The switch element is electrically connected with the electric power output end of the AC / DC power supply converting module and the main power supply output end. The standby power supply output end is electrically connected with the electric power output end of the AC / DC power supply converting module. The linear control module comprises a control switch, a first resistor, a capacitor and a second resistor. The control switch is electrically connected with the control signal output end. The first resistor is electrically connected with the control switch. The capacitor is electrically connected with the electric power output end of the AC / DC power supply converting module and the first resistor. The second resistor is electrically connected with the switch element, the first resistor and the capacitor.

Description

technical field [0001] The present invention relates to a power supply system, and in particular to a power supply system with low standby power consumption. Background technique [0002] Cooperate with reference figure 1 , is the circuit diagram of the existing switch control circuit. The switch control circuit 1 is electrically connected between a DC power VDC and a switch element 10 , and the switch control circuit 1 is used to control the switch element 10 to be turned on or off, and then determine whether the DC power VDC is connected to an electronic system PS. Wherein, the electronic system PS is electrically connected to the drain of the switch element 10 through the output resistors Ro1 and Ro2, and the terminals connected between the electronic system PS and the output resistors Ro1 and Ro2 are defined as power output terminals Vo1 and Vo2. [0003] The switch control circuit 1 includes a sense resistor RS, a control switch Q, a resistor R and a capacitor C. One...
