The invention discloses a method and a device for achieving a direct-current high-voltage power source with settable output voltage waveform and fluctuation region. A control signal CVKZ of an output voltage is formed by overlaying two paths A and B of independent control signal sources, wherein a periodic voltage signal exists in the path A and is adjustable in period, voltage amplitude and duty ratio, and a 0-10-voltage adjustable direct-current signal exists in the path B. The paths A and B can be used for independently controlling the output voltage of the power source. The CVKZ is used for controlling the duty ratio of the output voltage of a PWM (Pulse Width Modulation) device so that the duty ratio is changed along with the change of the signal CVKZ. The output voltage waveform and fluctuation region of the direct-current high-voltage power source with the PWM device as an exciter are set through adjusting the signal CVKZ. The method and device have the advantages that a trapezoidal wave and a triangular wave can be output; the fluctuation region, the peak time and the trough time of the trapezoidal wave can be set; constant-voltage or constant-current output can also be realized. The method and device can be applied to medical treatment, chemical industry, electrostatic spinning and scientific experiments.
Description
technical field [0001] The invention relates to a high-voltage power supply. In particular, it relates to a DC high-voltage power supply capable of setting output voltage waveforms and fluctuation regions. Background technique [0002] In recent years, high-voltage power supplies have been widely used in medical, chemical, electrospinning, and scientific experiments. At present, none of the high-voltage power supplies used has the function of setting the output voltage fluctuation area and fluctuation period. In the production field of high-voltage electrospinning, a DC high-voltage power supply that can set the output voltage waveform and fluctuation area is needed. The output voltage waveform of the power supply can be trapezoidal wave, triangular wave, and can also be stabilized. Set the fluctuation area and fluctuation cycle of its output voltage; the duration of the high voltage peak value of the power output can be set T 1， with high pressure valley sustained T 2，，...
