Abstract

Design and implementation of a digital controller for universal telecommunication power supply modules are presented. The paper emphasises on converter control strategy, and its implementation by means of parallel operated, dual 8-bit microcontrollers. One of the microcontrollers is employed for user interface purposes, such as long term records, display and alarm facilities, which are inherently slow processes. The fast processing speed required by output voltage setting, current limit, and load current sharing however, is fulfilled by the second microcontroller, which adjusts the output voltages of modules. The proposed dual-processor based digital controller provides an extended operating output voltage range, user programmable current limit setting, serial-communication based active load current sharing between modules, and automatic derating without extra hardware requirement. Overload and output short-circuit protection features are also software-controlled. The controller is tested successfully on six parallel operating, 1.8 W, 0-70 V telecommunication power supplies.

使用双8位微控制器的通用通信电源的数字控制

介绍了一种通用通信电源模块数字控制器的设计与实现。本文重点介绍了转换器的控制策略，并利用并行操作的双8位微控制器实现了该策略。其中一个微控制器用于用户界面目的，如长期记录，显示和报警设施，这些本身就是缓慢的过程。而输出电压设定、限流和负载电流分担所需的快速处理速度则由第二个微控制器来实现，该微控制器调节模块的输出电压。所提出的基于双处理器的数字控制器提供了扩展的工作输出电压范围，用户可编程的电流限制设置，基于串行通信的模块之间的主动负载电流共享，以及自动降额，而无需额外的硬件要求。过载和输出短路保护功能也由软件控制。该控制器在6个1.8 W 0-70 V通信电源并联上测试成功。
