电力机车经济四段半控整流微机控制系统

Economical Four Stage Semi control Commutation Microcomputer System of the Electric Locomotive

分析了我国电力机车经济四段半控整流控制系统的现状 ,并针对存在的问题设计出一种采用 8751单片微机控制的数字化控制系统。系统内设计了高分辨率的数字触发器和高精度的同步中断脉冲以及高精度快速 A/ D转换。

This paper discusses the status of the economical four stage semi control commutation systems for the electric locomotive in our country, and to the problems, a digital control system based on the 8051 chip microcomputer is given. The design adopts high resolution digital trigger, high precision synchronous interrupt pluse and high precision fast A/D converter.
