I. Introduction
High-voltage pulsed power supply is a power supply device that converts low-voltage input into high-voltage pulsed output by controlling the switching devices' turn-on and turn-off. Its working principle is mainly based on the characteristics of power electronic devices, such as MOSFETs and IGBTs. These devices can achieve turn-on and turn-off in an extremely short time, realizing the generation and regulation of high-voltage pulses.
High-voltage pulsed power supply has the following remarkable characteristics:
1. High-voltage output: capable of providing kilovolt or even higher high-voltage output to meet different application needs.

In biomedical fields, high-voltage pulsed power supply is widely used in electrophoresis, electroporation, cell disruption, and other techniques. For example, in electrophoresis, high-voltage pulsed power supply can provide a stable electric field intensity, allowing biological molecules to separate and purify under the action of the electric field. In electroporation technology, the pulsed electric field generated by high-voltage pulsed power supply can induce reversible perforation of cell membranes, promoting the introduction of drugs or genes. In addition, high-voltage pulsed power supply can also be used in tumor treatment with electric field therapy, destroying the cell membrane structure of tumor cells by generating high-intensity pulsed electric fields to achieve therapeutic purposes.
IV. Applications of High-Voltage Pulsed Power Supply in Environmental Protection Fields
In environmental protection fields, high-voltage pulsed power supply also plays an essential role. For example, in electrostatic precipitation technology, high-voltage pulsed power supply provides a high-voltage DC electric field for the precipitator, causing airborne dust particles to become charged and adsorbed onto the dust collection plate, thereby purifying the air. In addition, high-voltage pulsed power supply can also be applied in wastewater treatment and exhaust gas treatment, degrading organic pollutants through electrochemical redox reactions and reducing pollutant emissions.
V. Applications of High-Voltage Pulsed Power Supply in New Energy Fields
In the field of new energy, high-voltage pulsed power supply has significant application prospects in plasma ignition and fuel cells. For example, in plasma ignition technology, the high-energy pulses generated by high-voltage pulsed power supply can excite gas discharge to produce high-temperature plasma, which in turn ignites the fuel gas to achieve efficient combustion. In fuel cells, high-voltage pulsed power supply can provide the necessary electrical energy for the electrolysis of water to produce hydrogen, promoting the development of the hydrogen energy industry.
VI. Conclusion
In conclusion, high-voltage pulsed power supply, with its unique advantages, plays a crucial role in many emerging technology fields. With the continuous advancement of technology and the increasing demand for applications, the research and application prospects of high-voltage pulsed power supply will be even broader. In the future, it is necessary to further strengthen technological innovation and application expansion of high-voltage pulsed power supply to meet the development needs of different fields and promote the rapid development of related industries.
