The application discloses a high-voltage charging and discharging circuit based on digital control and an adaptive regulation method thereof, and belongs to the technical field of charging and discharging. The circuit mainly comprises an ARM microprocessor digital control module, a charging signal trigger module, a charging and discharging module, an isolation driving module and a signal isolation sampling module. The application introduces an ARM microprocessor digital control architecture on the basis of a traditional analog circuit. An ARM microcontroller generates a PWM signal to drive a power switching device for high-frequency switching control of a transformer, so that the input voltage is converted into a high-frequency square wave pulse voltage to charge a high-voltage pulse capacitor. The signal isolation sampling module samples the charging voltage value in real time, and a software control algorithm is combined to timely adjust the PWM signal, so that a charging closed-loop control is formed. When it is detected that the charging voltage value reaches a preset threshold value, the ARM microprocessor directly generates a discharging signal to drive the power switching device, so that the discharging action is completed. The control precision, response speed and autonomy of the charging and discharging are greatly improved.
