Design of High-voltage Electrostatic Generator Based on STM32

This paper introduced a high-precision high-voltage dectrostatic generator which utilized SIM32F103 as the main controller.The hardware and software design of the system were detailed.The full use of ample on-chip resources of STM32F103,such as ADC and the PWM output of timer,contributed to the small size and low cost of the system,The 16-bit PWM signals,generated by the timer on chip,served to adjust the output voltage accurately.The touch screen was responsible for the setting and display of output voltage,and the friendly humen-computer interaction was built.Experimental results indicated that this high-voltage static generator was of high precision and great practicability for application.
