摘要
提出了基于电压平方外环的直接功率控制策略,并结合单周期控制探讨了单相有源功率因数校正器(APFC)对输出功率变化快速响应的状况。在负载突变情况下,APFC能提升整个系统的响应速度。上述结论通过Matlab/Simulink仿真分析结果得到验证。
This paper presented a strategy of direct power control which is based on voltage squared outer loop, and one cycle control is combined with to discuss the quick response to the output power variation in terms of the single-phase active power factor corrector（APFC）. The whole system＇ s response speed is increased dramatically in the case of the suddenly-changed loads. The simulation results by means of Matlab/Simulink prove the above con- clusions.
