Description

technical field [0001] The invention belongs to the field of pulse power supply, and in particular relates to a nanosecond-level pulse power supply controlled by a thyristor. Background technique [0002] Pulse power technology is a subject technology that rapidly releases energy stored in a relatively long period of time in a short period of time. Pulse power technology is already a very widely used technology. It can generate extremely high voltage and high temperature in a short period of time. It can accelerate particles to a high speed and generate great force. It can also detect targets at a long distance. In industry, pulse power technology is used to treat waste gas and wastewater, VOC treatment, electrostatic dust removal, desulfurization, ozone generation, and food preservation. As we all know, the basic principle of pulse power technology is: energy (E) is equal to power (P) multiplied by power action time (t), that is: E=Pt; it can be seen that when the energy ...
