Problems solved by technology

[0005] The present invention proposes a portable rechargeable microsecond pulse power supply. Its purpose is to solve the problem that the existing microsecond pulse power supply needs to be connected to the mains or an external high-voltage DC power supply as power input, which is not easy to carry and cannot be used for a long time when the operating frequency is high To solve the problems of time and no load, design a miniaturized portable microsecond pulse power supply that does not need to be plugged in. It is powered by a rechargeable lithium battery pack. It has a simple and compact structure, small size, low cost, and is portable. Mains power; the pulse transformer is equipped with a demagnetization winding and an air gap, which makes the power supply suitable for no-load operation, suitable for occasions where it is difficult to obtain stable power supply, and used to drive small Power Low Temperature Plasma Reactor
