A floating isolated high voltage power supply

Abstract

The invention belongs to the field of power lines, especially a floating isolated high-voltage power supply. When the isolation voltage of the existing high-voltage power supply reaches tens of thousands of volts, the method of using an isolation transformer is gradually unfeasible. This is mainly because the isolation voltage cannot meet the requirements on the one hand. , on the other hand, the efficiency of the isolation transformer will decrease, and the volume will increase sharply at the same time. The following scheme is proposed, which includes a transmitting circuit, a receiving circuit and a DC-DC conversion circuit, and the transmitting circuit and the receiving circuit are electrically connected. And there is a magnetic shield between the transmitting circuit and the receiving circuit, the receiving circuit is electrically connected to the DC-DC conversion circuit, and the transmitting circuit includes an integrated circuit T5336 and an integrated circuit XKT-408A. The invention uses non-radiative magnetic coupling resonance to perform high-voltage isolation and energy transmission, the isolation voltage can reach more than 50,000 volts, and the positive polarity and negative polarity can be easily switched. It has the advantages of convenient adjustment, safety and reliability, convenient material acquisition, and small volume , compact structure and high efficiency.

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...
