：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。

The last step in training phase is refinement of the clusters found above. Although DynamicClustering counters all the basic k-means disadvantages, setting the intra-cluster similarity r may require experimentation. Also, a cluster may have a lot in common with another, i.e., sequences assigned to it are as close to it as they are to another cluster. There may also be denser sub-clusters within the larger ones.
