Abstract A detailed analysis of a multiple Boost converter based on the proposed instantaneous current control is presented. The Boost converter is used in the MW-level wind energy conversion system (WECS). The system topology is given to demonstrate the function of multiple structures and control strategy. To obtain a continuous mathematical model of the Boost converter, Fourier series are used to analyze the switching function. Then a steady-state analysis for low-frequency, and high-frequency component, and a closed-loop tracking performance analysis for dynamic response are provided to analyze the method proposed. The results show that the method can effectively restrain the low-frequency harmonics and has a fast dynamic response. The theoretical results are verified experimentally.
