Abstract-This paper introduced a high-precision high-voltag e electrostatic generator which utilized STM32F103 as the main controller. The h ardware and software design of the system were detailed. The full use of ample o n-chip resources of STM32F103, such as ADC and the PWM output of timer, contrib uted to the small size and low cost of the system. The 16-bit PWM signals, gene rated 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 human-computer interaction was built. Experimental results indica ted that this high-voltage static generator was of high precision and great pra cticability for application.
Key words-STM32F103； high-voltage static generator； voltage multiplying rectifier
