| 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... |
