基于所述ST7FLiteUS5和BTB12低端吸尘器演示板 Demonstration board on low-end vacuum cleaner based on the ST7FLiteUS5 and BTB12

is a demonstration board on low end vacuum cleaner based on the ST7FLiteUS5 and BTB12. This board implements a traditional design solution for a universal motor control circuit with a microcontroller as a driver. The electronic driver with TRIAC and microcontroller is cost effective and easy for designers to implement. Analog solutions are being progressively replaced by microcontroller designs even in low cost applications. The main reason of this evolution is primarily due to the possibility to of implementing a soft start function which allows the equipment to fulfill IEC 61000-3- 3 standard on inrush currents. Their advantages also include flexibility, using less external components and easy adaptation by simple software modifications.
