摘要 大功率电能变换装置的稳定运行,准确的相位信息至关重要。软件锁相环(SPLL)具有设计自由、适应性强等优点可快速获得电网电压的相位。本文通过分析SPLL原理,获得适用SPLL模型,并应用于大功率电能变换装置。仿真及试验表明所用SPLL能较好应用于大功率PWM整流装置。 Accurate phase information is crucial for most of the modern power-electronics apparatus. A software phase-lock loop (SPLL) has so many advantages, such as freedom of design. In this paper, considering of the operational principle of SPLL, the linearized model of SPLL is obtained. The relations between controller parameters and operation conditions are discussed. Simulation and experimental results indicate the designed SPLL can work well in a PWM rectifier.
