摘　　要：介绍了能驱动家用窗式空调器变频调速运行的变频器结构及其节能运行效果，较详细地分析了能满足空调电机变频要求的逆变器的主电路结构、产生ＳＰＷＭ信号的方法以及单片机实现的ｖ／ｆ协调控制；最后以ＫＣ２０型窗式空调压缩机为例。The make up of an inverter which can drive windowtype family air conditioner with variable frequency and spead is discussed in this paper including its energy saving effect. The main circuit structure of the inverter which can meet the frequency conversion requirement of the air conditioner motor, the way how to generate SPWM signal, and the V/f coordination control realized by means of single chip microcomputer are discussed in detail, and finally the practical result is given against KC 20 window type compressor as an example.
