一种单相全桥交流电子负载单周期控制策略

摘要

The paper first analyzes the principle of AC electronic load simulator based on single phase full bridge topology and introduces the one cycle control strategy of the load simulator.It then carriesout the simulation.The performance of one cycle control strategy and PID control strategy is compared from two aspects of load simulation accuracy and dynamic response speed.The one cycle control method of single phase full bridge AC/DC topology can not only improve electronic load simulation accuracy greatly, but also suppress power interference quickly.The results show that the one cycle control strategy of AC load simulators is effective and practical.%分析基于单相全桥拓扑结构的交流电子负载模拟器原理,介绍该负载模拟器单周期控制策略.在此理论基础上进行仿真实验,并从负载模拟精度和动态响应速度两个方面,将单周期控制策略和PID控制策略进行比较.仿真实验显示,单相全桥AC/DC拓扑结构结合单周期控制方法,不仅可以大大提高电子负载模拟精度,还能快速抑制电源干扰,是一种实用的交流电子负载模拟器控制策略.
