摘　　要：分析了洗衣机专用变频器的应用要求,针对洗衣机应用要求介绍了一种基于转差频率控制的效率最优控制算法及其效率最优的转差频率的获取方法。另外,还分析了该算法相对于恒压频比控制的优势。实验结果验证了基于转差频率控制的效率最优控制算法的有效性。The requirement for inverter in washing machine was analyzed. According to the requirement of washing ma- chine, an efficiency optimization control algorithm based on the slip frequency control was introduced, which tracked the maximum efficiency of induction motor. And a method to get the motor slip frequency of efficiency optimization was intro- duced. The advantages in comparison with V/F control were analyzed. The experiment result shows the validity of the VVVF control algorithm.
