北京市新技术产业试验区的金星超声波应用技术研究所最近完成了VMOS大功率管超声波发生器及VMOS超声波清洗机。。其超声波功率从150W至1000W,频率为35KC和28KC,构成了新型的超声波清洗机系列。VMOS功率器件与晶体管比具有高开关速度、低开关损耗,低拖尾电流、对温度不敏感、无二次击穿,栅极电压激励所需信号功率小等优点,这使得VMOS超声波清洗机发生器可靠性高、效率高、体积小、重量轻。采用大功率VMOS器件制做超声波清洗
Venus ultrasonic application technology research institute of Beijing New Technology Industry Experimental Zone recently completed VMOS high-power tube ultrasonic generator and VMOS ultrasonic cleaning machine. . The ultrasonic power from 150W to 1000W, the frequency of 35KC and 28KC, constitute a new series of ultrasonic cleaning machine. VMOS power device and transistor ratio with high switching speed, low switching loss, low tail current, temperature insensitive, no secondary breakdown, gate voltage excitation signal power required for small, which makes the VMOS ultrasonic cleaning machine occurs High reliability, high efficiency, small size, light weight. Using high-power VMOS device made of ultrasonic cleaning
