N2 - In the design of switching power converters, the filter is often added to the power input terminal. The input filter can not only reduce or eliminate electromagnetic interference and eliminate the switching harmonics of the input current of the converter,but also protect the converter and the load from being impacted when the voltage steps instantaneously. So it can improve the reliability of the system. But the input filter changes the dynamic performance of the system. When it is cascaded with a constant power load, it will cause the instability of the system and may even produce resonance. In this paper, a high-frequency current feed-forward compensation technique based on the resonant frequency of the input filter is proposed. It can suppress the oscillation and the waveform distortion of the system without changing the volume weight of the system and the original control structure. In order to guarantee the normal operation of the circuit, a Boost converter with a redundancy structure is presented in this paper. Firstly, the mathematical model of the system was analyzed. Furthermore, the simulation and experimental results were given to prove the correctness and feasibility of the proposed control strategy and topology structure.
