摘要
针对目前日益严重的供电电能质量问题,设计了一种用于两路或多路电源间的瞬控切换装置,当一路电源超限或断电后,该装置能够迅速切换至备用电源,以保证敏感负荷的稳定供电。首先介绍了该装置的整体设计框架,分析了该装置的工作原理;为提高该装置响应速度和控制精度,基于装置拓扑结构,对装置的驱动控制参数进行详细分析设计;最后对该装置的双电源切换过程进行了MATLAB建模仿真,结果表明该装置能够满足敏感和关键负荷对供电可靠性、连续性的苛刻要求。
In response to the increasingly serious power quality problem of power supply,a kind of instantaneous switching device between two or more power sources is designed.When one power source exceeds the limit or power failure,the device can quickly switch to backup power supply to ensure stable power supply for sensitive loads.Firstly,the overall design framework of the transient control device is introduced,and the working principle of the device is analyzed.In order to improve the response speed and control accuracy of the device,based on the device topology,the drive control parameters of the device are analyzed and designed in detail.Finally,a MATLAB modeling and simulation of the dual power supply switching process of the device is carried out.The simulation showed that the device can meet the demanding requirements of sensitive and critical loads for the reliability and continuity of power supply.
