Abstract: In order to adapt to energy conservation and emission reduction of home appliances market development needs in recent years,the washing machine manufacturers continuously designed three different consumption goods level-low, median, and high, to meet different customer groups. In order to improve the design efficiency of vertical inverter washer, to overcome the customization and integrated circuits requirements of different drive mode vertical inverter motor on the current detector circuit, in this paper, the standardization design of a current detection circuit performed in design development of the vertical inverter washer is described.
