摘　　要：μC/OS-Ⅱ是一种源码公开的实时操作系统,具有可裁剪、易移植、可靠、稳定等特点。作者选择μC/OS-Ⅱ系统作为软件开发平台,以电力行业通用的数字信号处理控制芯片TMS320F2812为硬件基础,进行了大功率整流电源控制器软硬件的设计,对存储器扩展技术、同步信号检测技术、任务分割和设计技术、抗干扰技术、恒压恒流控制技术等方面进行了论述,最后建立了一个小型实验装置验证该控制器的控制性能,并给出了试验结果。μC/OS-Ⅱ is a source-code publicized real-time operating system and it possesses following features： scalable, portable, reliable and stable. Choosing μC/OS-Ⅱ operating system as the platform for software development and taking DSP control chip TMS320F2812 that is widely used in power sector as the base of hardware, the design of hardware and software for the controller of high-power rectifier power supply is conducted. The techniques used in this design such as memory expansion, detection of synchronization signal, partitioning and design technology, constant voltage control and constant current control and so on are dwelled on. To verify the control performance of designed controller, a small experimental device is built and experimental results are given.
