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.

The purpose in this paper is the design of the control to switching power supply for small perturbations. By the theoretical analysis and calculation, with the output filter inductor current and filter capacitor voltage switching power supply as two state variables, the conclusion is that control of the output filter inductor current sampling do well in the anti-jamming. The simulation is made for verification. And comparing the results, the current control mode shows a very strong anti-interference ability.
