1.序言微处理机的发展已经在电子工业中引起了根本的变化。三年以前,微处理机还处于萌芽状态。现在,微处理机作为未来电子系统设计的有力工具和一种部件的观点为整个工业界所接受。特别是将微处理机引入电源和电源系统将对采用分立元件逐步进行新设计的现行实践产生显著的改进作用。现时,大部份电源是用包含分立元件和SSI/MSI集成电路的硬接线(hard-wired)逻辑设计的。计算机主要用来管理复杂的电源系 1. Introduction Microprocessor development has caused fundamental changes in the electronics industry. Three years ago, microprocessors were still in their infancy. The microprocessor is now accepted as a powerful tool and a component of future electronic system design for the entire industry. In particular, the introduction of microprocessors into power and power systems will have a significant improvement over current practices for the progressive design of new designs using discrete components. At the moment, most power supplies are designed with hard-wired logic that includes discrete components and SSI / MSI integrated circuits. Computer is mainly used to manage complex power system
