Aiming at reducing standby power consumption of switching power supply, a low standby power consumption control circuit for switching power supply is designed. The control circuit is composed of power switches, the driving circuit, the load detection circuit and the low power supply circuit. The control circuit effectively closed the input of switching power supply when the switching power supply is without load. The control circuit ensures the normal work of switching power supply when the switching power supply is with load. From the experiment results, the control circuit can effectively reduce standby power consumption of switching power supply.

New switching power supply gradually replaced the traditional linear power supply, but rarely has the operational status monitoring function. The design includes the main power supply and monitoring circuit design. The main circuit topology of the power supply is flyback DC-DC conversion body. The selection of the control circuit is current-controlled PWM chip. The monitoring circuit includes the design of detection and display circuit. The voltage and the current are detected respectively with the aid of the resistive subdivision in the testing circuit. The display circuit adopts PIC for sampling signal processing, and the dot matrix LCD12864 is used to display this power operating parameters. The power supply control system is simulated in Saber and Proteus software which monitors and observes the various parts of the circuit voltage and the output waveform. Finally, the hardware circuit is built and tested to prove the designed digital intelligent power feasibility.
