Emi Filter

Because of its high reliability and stable output, switching power supply is widely used in power electronic systems, but it is can not be ignored that its self-generated electromagnetic has a profound effect on the whole system. In order to suppress conducted interference generated by switching power supply, this article proposed a cascaded technology about the integrated EMI filter, and a simulation is carried out for the power converter output waveform. Experimental results show that this cascaded technology about the integrated EMI filter has a good inhibition on the harmonic.

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.
