A novel control strategy DPLL-QPR (Digital Phase-Locked-Loop and Quasi Proportional-Resonant) of current closed-loop for AC electrical load is proposed to implement a low-cost, fast and accurate control system. The closed-loop model analysis and the design of this control strategy of the system are presented in this paper. MATLAB is employed to analyze and optimize the parameters for digital controller. At last, a 100VA prototype has been built and tested to verify the theoretical analysis of the paper.
