Description

technical field [0001] The invention relates to a high-voltage pulse generating device and method, in particular to a bipolar nanosecond high-voltage narrow pulse generating device and method for generating bipolar nanosecond high-voltage narrow pulses. Background technique [0002] As an energy supply device, high-voltage pulse power supply has been widely used in fields such as desulfurization and denitrification, VOCs removal, and changes in physical and chemical properties of material surfaces. Researchers have done in-depth research on the relationship between the rising edge, pulse width, pulse polarity and other waveform parameters of the high-voltage pulse output by the high-voltage pulse power supply and the processing effect of the processed object, and obtained many research conclusions. There are many kinds of harmful substances in waste water and waste gas. Some substances are more sensitive to the polarity of the corona pulse. The narrower the pulse width and t...
