A rigid solid-state modulation switch module and its combined circuit

Abstract

The invention discloses a rigid solid-state modulation switch module and a combined circuit thereof. The switch module includes a trigger transformer with at least two secondary windings, at least two switch device assemblies. Each switching device assembly includes an electronic switching circuit, a solid-state switching device, a static voltage equalizing circuit, and a dynamic voltage equalizing circuit. The two input ends of the electronic switch circuit are respectively connected to the two ends of the corresponding secondary winding, the high voltage end of the two output ends of the electronic switch circuit is connected to the grid of the solid state switching device, and the low voltage end is connected to the solid state switch Device source connection. Both the static voltage equalizing circuit and the dynamic voltage equalizing circuit are connected in parallel between the source and the drain of the solid-state switching device. The electronic switch circuit is used to form the trigger pulse of the solid-state switching device from the positive and negative pulse trigger signals flowing through the primary of the trigger transformer. The invention also discloses a combined circuit formed by connecting several modules in series, in parallel, or in both series and parallel.

Description

Technical field [0001] The invention relates to pulse modulation switches of pulse modulators in pulse radar transmitters, electronic accelerators and other devices, as well as high-voltage direct current switches, etc., in particular to a rigid solid-state modulation switch module and a combined circuit thereof. Background technique [0002] Before the emergence of metal oxide field effect transistors (MOSFET) and insulated gate bipolar transistors (IGTBT) and their application technology matured, hydrogen charging thyristors were almost used in pulse modulators in radar transmitters and electron accelerators. , Vacuum electronic triode or similar vacuum electronic switch tube as pulse modulation switch. Because these electronic tubes not only have life problems, they also need to provide filament power and relatively large-power trigger signals, so that these vacuum electronic switching tube pulse modulation switches and their pulse modulators have short life, low reliability a...
