变频器是 使您能够控制交流电机速度的电子装置。背景：如果电机或交流电机直接由交流供电系统驱动，则仅有一个固定转速，具体取决于极数以及供电系统的供电频率。但是，如果某应用或生产过程要求具有可调的交流电压（即可控速度），则使用变频器。这些变频器能够 在恒定的交流电压的基础上产生 振幅（输出电压水平）和频率可变的交流电压。

因此，变频器连到电机的输入以产生一个能够调节的电压，从而满足客户要求。供电系统不再产生电机运行所需的频率和电压水平。变频器接管了该任务并 控制输出频率和输出电压。

变频器的主要优势是什么？ 可利用变频器将电机的速度从零无级地更改到所需的标称速度，并可达到大出许多的速度范围。 电机的转矩保持不变。 因此设备操作人员能够随时使其驱动技术适应其所需的条件。 变频器还允许直接切换转动方向。 一个简单的控制命令就可以改变相序。下端的交流电机随之以相反方向运转。
