This invention relates to a technique based on DSP technology of digital low-power, high-precision and high voltage generator, including a high voltage generate circuit 1, steady voltage driving circuit regulators 2, DSP control system 3, current / voltage circuit sampling tube 4, and driven circuit 5. The high voltage circuit provides negative voltage for X-ray tubes, and produces current in the X-ray tubes. Current / voltage sampling circuit 4 samples the voltage / current which is provided to X-ray tube by high voltage circuit 1, and the sampling signal will be transmitted to the DSP control system 3. DSP control system samples the signals using the built-in 10 D synchronous analog-to-digital converter, analysis and processing. Converter Implementation of a high voltage output circuits have a negative high voltage X-ray tube and the current stability testing. Then PWM control signal wave will be output based on the test results, and put it on regulators driving circuit 2 and flow-driven circuit 5, and a cl
