开关电源接口电路及故障监控系统的研究

Research of switch power supply's interface circuit and fault monitoring and control system

随着工业和电力电子技术的发展,开关电源越来越多地出现在了工业生产、工作生活等各个方面,其工作的稳定性以及工作效率的高低直接影响到开关的性能和使用领域。首先介绍了常用的开关电源监控接口电路工作原理,设计了一种基于无线射频传输的监控接口电路。实验结果表明,基于此类接口电路的开关电源故障监控系统工作稳定,实时性强,具有一定的借鉴意义。

With the development of the industry and power electronic technology, switching power supply were turning up in many aspects, such as industrial production, work and life. The performance of the switch and using areas were directly influenced by its work stability and the working efficiency. The commonly used switch power supply monitor interface circuit working principle was introduced. A kind of monitoring based on wireless rf transmission interface circuit was designed. The experimental results show that the switching power supply fault monitoring system based on this kind of interface circuit work is stable, strong real-time performance, and has a certain reference significance.
