摘要
当多个电源模块并联工作时,要解决的一个重要问题是负载电流的均分。均流的作用是使系统中的每个模块都能有效地输出功率,使系统中各模块处于最佳工作状态,保证电源系统稳定、可靠、高效地工作。文中介绍了几种均流技术的工作原理和特点,提出以微控制器为核心的强迫均流法对工作电流进行控制,给出了其系统设计和实验结果。该系统使用微控制器作为主控器件,可实现快速改变控制方案,而无需对硬件电路进行任何变动,能更好地满足工程需要。
When multi modules are in parallel operation,load current sharing technique is an important issue.Current-Sharing function is to effectively output power and keep the best working status for each module in the system,and to guarantee power system stable,reliable and work with high efficiency.This paper introduces working principles and features of some current-sharing technique,and proposes that forced current-sharing technique,in which microcontroller as a core,controls working current and obtains system design and experiment result.The system,relying on microcontroller as main control device,can realize fast change control scheme without change of hardware circuit,and can meet requirements of engineering.
