: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。

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
