It is a power supply that inputs AC mains or three-phase electricity and outputs DC voltage of thousands of volts or tens of thousands of volts. The output power ranges from hundreds of watts to several kilowatts. It can generally stabilize the voltage or current. The early DC high-voltage power supply converted AC mains or three-phase electricity into AC high voltage electricity through an industrial frequency high-voltage transformer, and then rectified and filtered it to obtain DC high voltage electricity.
