Dual closed-loop PI control is always used for SVG. On this occasion, SVG is easy to generate inrush current during start-up period. This paper analyzes the cause of inrush current''s generating. Therefore, a method that combines with the DC voltage increasing through step be step and capacitor energy outer loop control is designed to reduce magnitude of the inrush current. The simulation model of SVG is established in Matlab/Simulink to verify the proposed method. Finally, an experimental prototype of parallel SVG is developed to verify the method. The results from the simulation and experiment show that this method can effectively restrain the start-up inrush current and the SVG device can accurately compensate the reactive power generated by loads.
