| Abstract: | Designed a driving system for electromagnetic vibration exciter used for dropping pills machine. Choose PIC18F4523 microcontroller as control unit, TL494 chip as PWM signal source and full-bridge inverter power output mode. Output voltage and operating frequency are continuously adjustable, modulation accuracy are 0.1V and 1Hz. Its parameters are displayed by LCD in real time, Experiments show that the system fully satisfies the requirements of dropping pills test. |
