中文摘要

本文研究了瞬时平均电流共享方案(IACS)在三相不间断电源(UPS)并联运行中的适用性。通过建立离散时间模型进行控制环路分析与设计,探讨了系统稳定性与电流共享性能之间的权衡关系,旨在优化多机并联系统的动态响应与均流精度。

English Abstract

This paper investigates the suitability of instantaneous average current sharing scheme (IACS) for the parallel operation of three-phase uninterruptible power supply systems. A discrete-time model is developed for the analysis and design of the control loops. Some key issues are discussed based on the model and it is found that there is a compromise between system stability and current sharing per...
