: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。()
