Description
technical field [0001] The invention relates to an AC input low-power isolated fixed output high-voltage power supply circuit mainly used in the fields of industry, agriculture, national defense, scientific research and medical treatment. Background technique [0002] Most of the low-power high-voltage power supply products on the market are DC power supply, because the power supply volume of DC power supply can be much smaller than that of AC power supply, and the work is safer and more reliable. The traditional low-power high-voltage power supplies for AC power supply in the market are generally large in size, and their work safety and reliability are poor. With the development of science and technology, there is an increasing demand for high-voltage power supplies for AC power supply. Contents of the invention [0003] In order to adapt to the development and meet the market demand, the present invention provides a high-voltage power supply circuit with high-voltage out...
