Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a pulse power supply. Background technique [0002] The principle of pulse power supply is to make the primary energy have sufficient energy through slow energy storage, and then charge (or flow into energy) to the intermediate energy storage and pulse shaping system. , and finally quickly discharge to the load. [0003] Due to the intermittent power supply characteristics of pulse power supply, it has been widely used in many fields. For example, high-energy physics, particle accelerators, processing of metal materials, food sterilization, environmental dust removal and sterilization, etc., all require such a reliable pulse energy, high energy, adjustable pulse width and frequency, bipolar , Flat top voltage waveform. No matter what application this high power pulse power supply is used for, the high voltage pulse power supply is a core part of its design. Traditional...

Problems solved by technology

Traditional high-power pulse power supplies generally use power frequency transformers to boost the voltage, and then use magnetic compression switches or rotating spark gaps to obtain high-voltage pulses. Therefore, most of them are relatively bulky, and the range of pulse frequencies obtained is limited. Its repetition frequency is difficult to adjust, and the pulse waveform is easy. Variation, lower reliability, more difficult control, higher cost
