：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。()

用GAL16V8设计可变长度序列信号发生器，在掌握伪随机序列性质的基础上，设计给定长度的伪随机序列信号发生器，也即设计给定n后（n为移位寄存器的级数）最长线性反馈移位寄存器序列。并在给定n产生的最长序列的基础上，截短出课题给出的序列长度，并用FM软件对可编程器件GAL16V8进行编程，以实现长度不同的序列信号发生器。(GAL16V8 design variable-length sequence signal generator based on the master pseudo-random sequence nature, the design of a given length pseudo-random sequence
Signal generator, designed for the series) up to linear feedback shift register sequences given n (n is the shift register. And given n
Sequence length given by the subject on the basis of the longest sequence, truncated, and FM software for programming the programmable device GAL16V8, in order to achieve
Different length of the sequence signal generator.)
