Description

technical field [0001] The invention relates to pulse modulation switches of pulse modulators in devices such as pulse radar transmitters and electron accelerators, and high-voltage direct current switches, etc., in particular to a rigid solid-state modulation switch module and a combination circuit thereof. Background technique [0002] Before the appearance of Metal Oxide Field Effect Transistor (MOSFET) and Insulated Gate Bipolar Transistor (IGTBT) and their application technology matured, hydrogen-filled thyristors were almost always used in pulse modulators of radar transmitters and electron accelerators. , vacuum electron triode or similar vacuum electron switching tube as a pulse modulation switch. Because these electron tubes not only have life problems, but also need to provide filament power and trigger signals with relatively large power, these vacuum electronic switching tube-type pulse modulation switches and their pulse modulators have short life, low reliabili...
