The invention relates to a method for restraining 4-order Boost converter resonance. A compound-control closed loop topological structure is adopted; on a basis of conventional dual-closed-loop feedback control, current in a front-stage LC filter circuit is subjected to high-pass filtering, and acts on a system control terminal at certain proportional gain; a feedforward compensation technology for the 4-order Boost converter based on high frequency current at the resonant frequency of an input filter is designed; according to the compensation technology based on the high frequency current signals at the resonant frequency of the input filter provided by the invention, the stable output power range is expanded, and the system stability is reinforced under the premise of not changing the original system structure; the resonance phenomenon of the system can be effectively restrained and the circuit can be protected; and in addition, the compensation technology based on the high frequency current signals at the resonant frequency of the input filter provided by the invention can be widely applied to the fields of independent power supplies and transportation, such as pure electric vehicles, ships, submarines and the like, and is expected to be widely applied to the future electric power systems.
