摘要
滚筒洗干一体机兼顾清洁和烘干衣物功能,市场需求量稳步增长,降本需求也持续存在。从系统角度对洗干一体机的需求进行分析,提出了洗干一体机驱动控制器新拓扑结构。根据洗干一体机运行工况,分时复用风机,在洗涤和脱水模式下,利用风机定子绕组的电感特性取代网侧电抗器,降低了系统成本。然后,结合双逆变电路的拓扑结构,采用单相APFC优化网侧电流,降低网侧谐波,提高母线电压幅值,增加了滚筒电机高速脱水带载能力。最后仿真验证了本方案的有效性,为后续产品研发提供新技术思路。
The drum washing and drying machine has the functions of cleaning and drying clothes,the market demand for the drum washer-dryer is steadily increasing,and the demand for cost reduction also continues.Analyzing the needs and proposing a new topology of the drum washing and drying machine.According to the operating conditions,time-sharing multiplexed fans,in the washing and drying,the inductance characteristics of the stator winding of the fan are used to replace the grid-side reactor,which reduces the system cost.Then,combined with the topological structure of the dual inverter circuit,APFC is used to optimize the grid-side current,reduce grid-side harmonics,increase the amplitude of bus voltage,and increase the highspeed dehydration loading capacity of the motor.Finally,the simulation verifies the effectiveness of this scheme and provides new technical ideas for subsequent product development.
