一种大功率变频器系统的光纤通信方案
An Optical-fiber Communication Scheme of High-power Converter System
摘要
Abstract
Based on the parallel structure of high-power converter system,a high real-time and high synchronization optical-fiber communication scheme was proposed.The on-fly transmission ensures that the communication between the controllers has a low delay,and the clock synchronization algorithm compensates the time-difference between the master-controller and slave-controller,which ensure clock synchronization of all the controllers in the system to reduce circulation and its harm.When the system needs to run down or has a serious fault,the system could respond in time by changing the number of slave controllers in the optical-fiber communication network actively or passively,which provided flexible communication solutions for high power converter systems.The experimental results show that the proposed optical-fiber communication scheme is effective.关键词
