一、引言本文提出的微型机可编程序电源,不仅可以用程序控制其输出电压(或电流)的直流、交流状态,亦可控制与电压、电流成比例的物理量(如伺服电机的转速等);而且可以产生各种波形;特別是可以显示程序图形。为进一步发挥微处理机的作用,本文给出了单微处理机分时多路输出的方案。这是解决单微处理机多相输出可编程序电源的有效途径。用此可构成多相输出多功能的万用信号源。这是智能仪器和计算机辅助测试所不可缺少的。微型机可
I. INTRODUCTION The microcomputer programmable power supply proposed in this paper can not only control the DC and AC states of its output voltage (or current), but also control the physical quantities proportional to voltage and current (such as the rotating speed of servo motor, etc.) ; And can produce a variety of waveforms; In particular, can display the program graphics. In order to further play the role of microprocessor, this paper gives a single microprocessor time-sharing multi-output scheme. This is an effective way to solve the single-microprocessor multiphase output programmable power supply. Multi-phase output can be used to form a versatile multi-purpose signal source. This is indispensable for smart instruments and computer-aided testing. Microcomputer can
