Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage conversion, in particular to a portable high-voltage direct current generator. Background Art

[0002] The ZGF DC high-voltage generator, also known as a DC high-voltage generator, also includes various types of generators, including DC generators, high-voltage generators, high-voltage DC generators, portable DC high-voltage generators, medium-frequency DC high-voltage generators, high-frequency DC high-voltage generators, and AC / DC high-voltage generators. The DC high-voltage generator utilizes a high-frequency voltage multiplier circuit, the latest PWM high-frequency pulse-width modulation technology, closed-loop regulation, and high-voltage feedback, significantly improving voltage stability. It utilizes high-performance, high-power IGBT devices and their drive technology, and employs special shielding, isolation, and grounding measures based on electromagnetic compatibility theory. This ensures the DC high-voltage generator's high quality, portability, and the ability to withstand rated voltage discharge without damage.

[0003] After searching, a Chinese patent with publication number CN213484287U discloses a high-voltage DC generator for a power switching circuit. The key technical features of the generator are: a control and distribution box, a first fixed block fixedly connected to one side of the control and distribution box surface, a rotating shaft rotatably connected within the first fixed block, a second fixed block rotatably connected to the end of the rotating shaft away from the first fixed block, a box cover fixedly connected to the side of the second fixed block away from the control and distribution box, the box cover rotatably connected to the control and distribution box, and a first placement slot provided on the side of the control and distribution box surface near the first fixed block. This utility model is used for a high-voltage DC generator for a power switching circuit. The first placement slot allows the DC high-voltage generator to be directly placed in the control and distribution box. It is compact, versatile, and convenient for field use. The silicon stack allows it to have different connection states with the high-voltage capacitor, thereby achieving high-voltage outputs of opposite polarity. This makes it a low-cost and easy-to-operate DC high-voltage generator.
