一、前言随着微型计算机的普及,在电源系统中也开始应用微计算机。在国外,大型计算机电源系统,宇航用太阳能电源系统,原子能电源系统,电力拖动电源系统,电报电话电源系统等广泛采用微处理机进行控制。这就打破了原来计算机电源系统为计算机服务的“单向”作用。随着微处理机的应用,计算机反过来不但作为电源线路辅助设计工具,而且直接控制计算机电源系统。形成一种计算机技术和电源技术之间互相渗透、互相影响的交互作用。本文介绍的一种用微型机控制具有正负极性的多种电压输出的可控硅整流电源就是微处理机在电源中的一种应用,也是它们交互作用的反映。这种可 I. INTRODUCTION With the popularization of micro-computers, micro-computers have also begun to be used in power systems. In foreign countries, large-scale computer power system, space solar power system, atomic power system, electric drive power system, telegraph telephone power system widely used microprocessor control. This broke the original computer power system for computer services, “one-way” role. With the application of microprocessors, the computer not only as a secondary power line design tools, but also directly control the computer power system. The formation of a computer technology and power technology mutual infiltration, interaction of each other. This article describes a microcomputer with a positive and negative control of a variety of voltage output of the SCR rectifier power supply is the microprocessor in the power of an application, but also a reflection of their interaction. This can be
