Study on SVG Simulation with the Voltage and Current Dual Closed-Loop PWM Control Strategy

This paper first introduced the SVG main circuit and the basic principles of SVG, then finished SVG modeling in dq coordinate process. Then an SVG direct current control method was proposed as well. Considering stability requirement to the DC side voltage, the paper designed voltage and current dual closed-loop PWM control system. Finally, SVG system was simulated using the Matlab/simulink. Results show that SVG has a good dynamic performance, verifying the correctness and validity of the dual closed-loop control.
