Abstract

In order to solve the power quality problems, such as low voltage output, power instability and voltage fluctuation. A combined structure of two order low-pass filter and high gain FIBC converter is presented. By way of disposing the resonance phenomenon caused by the cascade of filter and converter, this paper designs a kind of stabilizer which can restrain the resonance effectively. It can suppress the oscillation and distortion of the system without increasing the volume weight and power loss of the system. Firstly, the mathematical model of the system is established. Then, the stability of the system is analyzed by using Lyapunov method, and the feasibility of the method is proved. The simulation results verify the correctness and effectiveness of the proposed control strategy and topology.
