摘要:A switching-based SVPWM control method for three-phase active power filter is proposed in this paper. First, error model of the switched system is established. And then, according to the space voltage vector diagram and three-phase supply voltage waveforms, the supply voltage is divided into six sectors. In each sector, a combination of switching subsystem is set up according to the requirement of quadratic stability condition. Finally, the common Lyapunov function is selected and therefore, the subsystem is determined, which has minimum derivative of Lyapunov function and meets the conditions above. The validity of the proposed control method is proved with Matlab/Simulink and experimental results
