鉴于采用总线通讯间隙供电的方式可以有效降低布线成本,提出了一种基于通讯总线和单相PWM的小功率电源系统的设计方案.介绍了系统总体结构、设计原理,详细阐述了实现总线小功率供电的软硬件,并分析和测试了系统功能.实践证明该系统具有高效、稳定等优点,对于小功率节点的总线技术的研究和发展具有一定意义.

In view of the advantage of low cost by using Bus space power supply, a project of less power electrical source system on communication BUS and single-phasePWMis presented. The system frame and design elements are introduced. The hardware and software about the less power electrical source system on BUS are particularly expatiated, and the functionof system is analyzed and tested. The practice shows that the system has higher efficiency and stability, and has great signification for research and development of the BUS technology with less power node.
