Problems solved by technology

[0003] At present, portable DC voltage generators usually use medium (high) frequency doubler circuit, PWM pulse width modulation technology and high-power IGBT (insulated gate bipolar power tube) device. Although the volume is small, the disadvantage is that the power supply capacity is small, The radio interference is relatively large, which cannot fully meet the research and experimental research related to UHV DC

[0004] Although the DC voltage generator using 50Hz power frequency power supply as the rectification source can make up for the shortcomings of the portable DC voltage generator, most of them are fixed test devices, and relevant experimental research cannot be carried out on site.
