Floating ground isolation high-voltage power supply

Abstract

The invention belongs to the field of power lines, and especially relates to a floating ground isolation high-voltage power supply. For the problem that when the isolation voltage of an existing high-voltage power supply reaches tens of thousands of volts, the method of using an isolation transformer is gradually infeasible, the isolation voltage cannot meet the requirement, the efficiency of theisolation transformer is reduced, and the size can be sharply increased, the following scheme is proposed: the power supply comprises a transmitting circuit, a receiving circuit and a DC-DC conversioncircuit, the transmitting circuit is electrically connected with the receiving circuit, a magnetic shield is arranged between the transmitting circuit and the receiving circuit, the receiving circuitis electrically connected with the DC-DC conversion circuit, and the transmitting circuit comprises an integrated circuit T5336 and an integrated circuit XKT-408A. High-voltage isolation and energy transmission are conducted through non-radiative magnetic coupling resonance, the isolation voltage can reach 50,000 volts or above, positive polarity and negative polarity can be switched conveniently, and the floating ground isolation high-voltage power supply has the advantages of being convenient to adjust, safe, reliable, small in size, compact in structure, high in efficiency and the like, and materials are convenient to obtain.

Description

technical field [0001] The invention relates to the technical field of power lines, in particular to a floating isolation high-voltage power supply. Background technique [0002] In the application fields of medicine, scientific instruments, power lines, etc., DC high-voltage power supply is an essential component, such as X-ray machine, laser light source, spectral analysis detection, non-destructive testing, semiconductor manufacturing, capillary electrophoresis, non-destructive testing and other fields. The operation, control, measurement, modulation, and waveform generation of the DC high-voltage power supply are often involved in the application of the DC high-voltage power supply. Therefore, operations such as DA, AD, PWN control, and identity information identification need to be performed on the high-voltage power supply. Since the general semiconductor devices are made of materials such as silicon, germanium or gallium arsenide, their conductivity is between good co...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the isolation voltage of the high-voltage power supply in the prior art reaches tens of thousands of volts, the method of using an isolation transformer becomes gradually unfeasible. This is mainly because the isolation voltage cannot meet the requirements on the one hand, and the isolation transformer The efficiency will be reduced, and the volume will increase sharply at the same time, and a floating isolation high-voltage power supply is proposed
