SFC逆变桥驱动电路设计

摘要

本文介绍了SFC静止变频器逆变桥部分晶闸管组驱动触发电路的设计。首先简介了SFC的组成结构和工作原理，由整流桥的工作状况及两组桥合作工作的状况，从而提出驱动逆变桥存在要与整流桥同步触发的问题。而后利用分立元件搭建了一个简易驱动电路，并使用Multisim电路仿真软件验证了其有效性，进而给出装置应用的集成电路驱动电路，最后给出触发脉冲实验结果。%The article introduces thyristor trigger circuit design of inverter bridge of SFC static frequency converter. At first it describes the composition and working principle,talks from the working status of rectifier to the cooperating status of two bridges,thereby proposes a question about synchronous trigger between inverter bridge and rectifier bridge. It uses individual device to build a simple drive circuit,and validates the effect by Multisim simulation software,furthermore issues the inverter drive circuit which is consisted of integrated circuit. Final y,it shows the results of pulse generating experiment.
