Peng Yi, Peide Sun, Daxing Chen · 2011
This paper implements the double-loop control system of Three-level PWM Rectifier based on the mathematical model. This system achieves the same-phase between current on line side and input voltage by means of electric current loop and make the output voltage follows the given voltage by means of electric voltage loop. Finally, the experimental results the feasibility of the controller, which can achieve small current harmonic wave, steady DC voltage and strong capacity of resisting disturbance.
