softwarephaselockedloop
在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。(Frequency or voltage fluctuations in three-phase unbalanced case, the hardware lock is difficult to accurately detect the fundamental positive sequence phase. In the space vector PWM rectifier with decoupling control algorithm based on the software used in the PWM rectifier PLL control system, and use simulation and experimental verification of the feasibility. Experimental results show that the solutions to address the voltage and frequency fluctuations of the phase unbalanced three-phase synchronization issues, and the project has a certain reference value.)

：介绍了一种基于数字信号处理器（DSP）的移相调频（Phase-Shifted and Frequency-Varied，PSFV）PWM控制
逆变电源，给出了主电路拓扑结构，分析了其控制原理并设计了其控制程序流程图。新颖的PSFV 控制能够实现输出
电压90％的调整率，输出电流波动小于单纯移相调功PWM方式，并在轻载时保持连续。功率开关器件零电压零电流
通断（Zero-Voltage-Zero-Current Switching，ZVZCS）软开关的实现，有利于进一步提高开关频率和降低开关损耗。采用
高性能的专用DSP 芯片TMS320F2812 实现了系统的数字控制，满足了系统控制的灵活性和实时性，减小了系统的
体积和生产成本。仿真分析和实验结果证明了此控制模式的可行性与合理性。()
