摘要
提出了一种采用控制器局域网(Controller Area Network,简称CAN)现场总线进行通信,实现DC/DC变换器并联均流的控制方案。该方案采用数字均流方法,提高了电源系统的可靠性和抗干扰能力。利用DSP芯片内部的CAN控制器,使设计简化,减少硬件开销。该方案在250W的DC/DC通信电源并联系统中得到了成功的应用,可以作为一种带有总线竞争的通用数字均流技术。
A current-sharing scheme with communication by Controller Area Network(CAN) field bus is offered in this paper.The digital controlled current-sharing method is adopted in the scheme in order to improve the reliability and anti-interference capacity of power supply system.CAN controller on Digital Signal Processor(DSP) chip is used for simple design and less cost.This scheme has been used successfully in 250W system of paralleled DC/DC communication power supplies,and it can be used as a universal digital current-sharing technology with competition on CAN bus.
