This article presents the design of a portable electrostatic high-voltage power supply capable of constant current and constant voltage control,as well as presetting high-voltage current and voltage,to meet the needs of electrostatic spraying high-voltage power sources for portable beauty instruments.The high-voltage pulse transformer employs a single-side drive method,where the driving narrow pulse signal source is provided by an AVR microcontroller.A closed-loop control system is formed between the high-voltage side current acquisition signal and the MCU,which fine-adjusts the narrow pulse width to achieve constant current control.Similarly,the high-voltage side voltage acquisition signal forms a voltage acquisition closed-loop control with the microcontroller,adjusting the power supply voltage of the single-side boosting circuit to achieve high-voltage constant voltage control.By utilizing the PID control algorithm,the constant current and constant voltage control can achieve rapid and stable output current or voltage.The designed high-voltage power supply exhibits high output stability,strong anti-interference capability,and improved spraying effect and battery life for electrostatic spraying equipment.
