摘　　要：针对传统电子负载对电能的浪费,研究与设计的能馈式单相交流电子负载能有效地将电能回馈,达到能源二次利用的目的。以全控型器件形成的"背对背"H桥为主电路,分析了整个系统的基本工作原理。在Matlab仿真平台上对准PR控制算法中的重要参数对控制效果的影响进行了验证分析,并将PI及准PR控制算法进行结合互补应用于设计中。搭建了Matlab/Simulink模型和基于TMS320F28335样机系统,仿真和实验结果表明了所采用控制策略的可行性。For the electricenergy waste of traditional electricity load, energy feedback type single- phase AC electronic load was researched and designed which could effectively feed back energy-, achieve the goal of reutilization of energy. The type control device was formed to ＂back to back＂ H-bridge as main circuit, the basic working principle of the whole system was analysed. The influence of the important parameters for the PR control algorithm on the control effect was verified and analyzed in the Matlab simulation platform, and the PI and quasi-PR control algorithm combined with complementary were applied to the design. A Matlab/Simulink model and the prototype system based on TMS320F28335 were set up. The simulation and experimental results show that the control strategy is feasible.
