Problems solved by technology

[0003] One is that the voltage doubler rectification method causes the high voltage generating device to have too little load capacity, and the current is generally in the microampere level, usually not exceeding 10 milliamperes;
[0004] Second, the stability of DC high voltage is worrying, because under heavy load, DC high voltage is too high through a single step-up, which is particularly easy to magnetically saturate high-frequency transformers.

Description

technical field [0001] The invention relates to a 100,000-volt DC high-voltage generating device, which is mainly used in high-voltage electrostatic dust removal, high-voltage electrostatic spraying, high-voltage electrostatic seed selection, high-voltage electrostatic painting and powder electrostatic spraying equipment. Background technique [0002] The traditional DC high voltage acquisition is obtained by pulse high voltage through voltage doubler rectification. The fundamental frequency pulse signal is generated by the oscillating circuit, amplified by the power amplifier circuit, and then output a high-voltage signal of about 10kV after multiple times of voltage doubling and rectification under the one-time boost of the high-frequency pulse transformer. The DC high voltage formed in this way mainly has two problems: [0003] One is that the voltage doubler rectification method causes the high voltage generating device to have too little load capacity, and the current ...
