Capacitive Load

The circuit of series switching power supply based on voltage and current dual-loop control is proposed, which can work in the voltage range from 12V to 90V. It is less influence to working state when capacitive load is accessed. The circuit have the function of quickly response, short circuit protection and overcurrent protection. The power supply have advantages of low-cost and working stability, which can be used to different various industry alarms and blasting signal lights in the wide voltage range.

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.
