：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。()

TCPIPTutorial
In the TCP/IP protocol suite, TCP is the intermediate layer
between IP below it, and an application above it. Using TCP,
applications on networked hosts can establish reliable
connections to one another. The protocol guarantees in-order
delivery of data from the sender to the receiver
Streams of data called segments are used by TCP peers to
speak to each other. The segments can be quite large, so TCP
breaks up the segments into smaller units of data. These units
are encapsulated in the TCP packet that is passed to the IP
protocol. Each unit of data is assigned a sequence number,
which becomes part of the TCP packet. At the receiving end, the
TCP module uses the sequence numbers in the packet to
reconstruct the user data in the correct order.
