：介紹了一種基于數(shù)字信號處理器（DSP）的移相調頻（Phase-Shifted and Frequency-Varied，PSFV）PWM控制 逆變電源，給出了主電路拓撲結構，分析了其控制原理并設計了其控制程序流程圖。新穎的PSFV 控制能夠實現(xiàn)輸出 電壓90％的調整率，輸出電流波動小于單純移相調功PWM方式，并在輕載時保持連續(xù)。功率開關器件零電壓零電流 通斷（Zero-Voltage-Zero-Current Switching，ZVZCS）軟開關的實現(xiàn)，有利于進一步提高開關頻率和降低開關損耗。采用 高性能的專用DSP 芯片TMS320F2812 實現(xiàn)了系統(tǒng)的數(shù)字控制，滿足了系統(tǒng)控制的靈活性和實時性，減小了系統(tǒng)的 體積和生產(chǎn)成本。仿真分析和實驗結果證明了此控制模式的可行性與合理性。

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.
