High-frequency and high-voltage electronic switch with programmable control over conduction time

Abstract

The invention relates to a high-frequency and high-voltage electronic switch with programmable control over conduction time. The electronic switch comprises a switching tube stack drive end, a coupling inductor, an MOS transistor, an inverted power source, a drive circuit, a trigger, an oscillation circuit and a programmable logic controller. The trigger is connected with the oscillation circuit and the programmable logic controller. The drive circuit is connected with the trigger, the inverted power source and the grid electrode of the MOS transistor. The drain electrode of the MOS transistor and the inverter power source are connected with a primary coil of the coupling inductor. A secondary coil of the coupling inductor is connected with the switching tube stack drive end. Compared with the prior art, the electronic switch can bear kilovolts of high voltages and dozens of amperes of current and is high in conduction speed, low in conduction resistance, and the length of the conduction time and the conduction frequency each second can be accurately controlled.

Description

technical field [0001] The invention relates to an electronic switch, in particular to a high-frequency and high-voltage electronic switch with programmable conduction time. Background technique [0002] Although some traditional mechanical switches can withstand high voltage and high current, they cannot precisely control the conduction time and the number of conductions per second. The most important point is that the high-voltage mechanical switch will generate an arc at the moment of conduction, and the arc will be superimposed on the energy wave, causing the energy wave passing through the switch to be strongly disturbed, resulting in burrs or deformation, while ordinary electronic switches can do Accurate control of the conduction time and the number of conductions per second, but it is not easy to meet the requirements of speed and high voltage and large current. Contents of the invention [0003] The object of the present invention is to provide a high-frequency a...
