Description

technical field [0001] The invention relates to a high-voltage pulse generating device capable of generating high-voltage pulses with voltage settings. Background technique [0002] At present, the application range of high-voltage pulse discharge is extremely wide. Not only has new exploration and discovery been obtained in water treatment, but also more and more applications have been applied in the fields of crack detection of metal pipelines. Many high-voltage pulse generators that can generate high-voltage pulses have appeared on the market, but most of the high-voltage pulses that this type of high-voltage pulse generator can generate are fixed at a certain voltage or adjustable fixed high-voltage pulses. [0003] Chinese invention patent application CN 86 1 02439 A discloses a circuit device for generating high-voltage pulses, which includes a transformer, a secondary winding of the transformer and at least two primary windings, at least one diode and a switching circ...
