Problems solved by technology

Finally, through a small switch circuit, 400VDC is sent to the wire passing through the coil in the form of a pulse, and finally the driving voltage is induced on the coil to drive the conduction of the IGBT tube. It is complex, and has higher requirements for the small switch used to drive 400VDC into a pulse at the end. The response speed must be fast, and the power requirement is also high.
For the existing high-pressure processing module, the manufacturing process is very cumbersome and difficult. The cumbersome and difficult process can easily lead to poor performance of the product, and even directly cause the switch to be directly damaged.
Another fatal shortcoming of the existing high-voltage and high-current electronic switches is that the linearity of the front edge of the pulse waveform passing through the switch is poor.
[0003] For the thyristor control module, the existing method is to drive a thyristor with a magnetic ring. We know that high-voltage and high-current electronic switches generally consist of one hundred to several hundred thyristors. It is conceivable that the module manufacturing process of the existing method is very difficult complicated

Description

technical field [0001] The invention relates to an electronic switch, in particular to a high-voltage and high-current electronic switch. Background technique [0002] The main components of the existing lightning strike high-current electronic switch are divided into a drive circuit module, a high-voltage processing module, and a thyristor control module. The working principle of the existing drive circuit module is ordinary DC / AC conversion, and then boosted to 350VAC through a transformer, and then rectified to 400DC, and placed in an energy storage capacitor for backup. Finally, through a small switch circuit, 400VDC is sent in the form of pulses to the wires passing through the coil, and finally the driving voltage is induced on the coil to drive the conduction of the IGBT tube. It is complicated, and the small switch used to drive 400VDC into a pulse has higher requirements, and the response speed must be fast, and the power requirement is also higher. For the existi...
