1794-IJ2数字量模块
变频器主要由整流（交流变直流）、滤波、逆变（直流变交流）、制动单元、驱动单元、检测单元微处理单元等组成。变频器靠内部IGBT的开断来调整输出电源的电压和频率，根据电机的实际需要来提供其所需要的电源电压，进而达到节能、调速的目的，另外，变频器还有很多的保护功能，如过流、过压、过载保护等等。随着工业自动化程度的不断提高，变频器也得到了非常广泛的应用。
中文名：变频器，外文名：Variable-frequency Drive、AC Drive。简称：VFD，类别：电机控制设备，应用：变频技术与微电子技术

电源管理：指如何将电源有效分配给系统的不同组件。电源管理对于依赖电池电源的移动式设备至关重要。通过降低组件闲置时的能耗，的电源管理系统能够将电池寿命延长两倍或三倍。
过压保护：当被保护线路的电源电压一定数值时，保护器切断该线路；当电源电压恢复到正常范围时，保护器自动接通。
