摘 要

 本文介绍了一种可编程控制数字移相晶闸管触发电路。利用EDA工具中的硬件描述语言（Verilog HDL），遵照IP核的设计标准完成了数字化三相晶闸管触发电力的设计。该电路以CPLD为核心，经过CPLD的仿真测试实验证明了设计的正确。该电路具有相序自适的功能，稳定性好，适用于三相全控整流，调压场合，逆变系统的晶闸管触发。
  该晶闸管触发器采用集成放大器，通过直接相位比较形成移相触发脉冲，简单而具有优良的适应性和控制品质，可直接应用到实际的工程电路，而且成本也很低。

Design on Communication Switch Power Supply

Abstract

 Based on the technology of EDA(Electronic Design Automatic),compplied with the standard of IP design ,the core for the teiggering thyristor eircuit of three-phases is proposed ,and simulated with EDA software and verified by CPLD(Complex Programmable logic davices).The circuit implemented by IP core can be applied to trigger the thvristor of three phases rectifiler and inverses system.The precision of the phase shift can work with the frequence of 50Hz or 60Hz.，
