摘要
针对当前直流双电源切换系统运行安全性低,可靠性差的特点,提出一种基于静态开关的设计方法。该方法使用IGBT控制电路的通断,当其中一路供电发生故障时,可以自动切换到另一路供电。在一台直流双电源切换装置样机上进行了实验研究,实验结果表明,该直流双电源切换装置有很高的可靠性,具有较好的实际应用价值。
Aiming at the low security and poor reliability of the current DC dual power supply switching system,a design method based on static switch is proposed.The method uses the switch transistor IGBT control circuit,which can automatically switch to another power supply when the power supply failure occurs.Experimental study was conducted on a prototype of a DC dual power supply switching device.The results show that the DC dual power supply switching device is of high reliability and practical value.
