Abstract:
Combining switching control with space voltage vector,a method which applies to three-phase APF considering saturation limiting was proposed. First,error model of switching system of three-phase APF was established. A novel conservative stability criterion was found for saturation limiting based on Lyapunov stability theorem and convex set theory. And then according to space vector figure and wave-form,three phase supply voltage was divided into six sectors. Switch subsystem combination which meets quadratic stability requirement was chosen in each sector from convex stability requirement. The subsys-tem which made Lyapunov derivation the minimum was chosen in the subsystem combination which met quadratic stability requirement. Finally,the simulation analysis and experimental results proved the cor-rectness and feasibility of the proposed method.
