A high-efficiency pulse power generation circuit for degaussing switches based on rsd

Abstract

The invention discloses an RSD-based demagnetizing switch high-efficiency pulse power generation circuit which can be applied to the fields of high-power microwaves, nuclear physics technologies, pollution purification and the like. A traditional RSD pulse power generation circuit needs to use a magnetic switch to be matched with switching-on of an RSD, but the size of the magnetic switch is verylarge, so that the size of the traditional RSD pulse power generation circuit is easily too large. Meanwhile, when the RSD is triggered, energy consumed by a traditional RSD pulse power generation circuit cannot be ignored. Under the condition that a magnetic switch is not used, another semiconductor switching device RBDT is used for assisting the RSD so as to prevent the RSD from being damaged due to the fact that the value of current flowing through the RSD is too large when the RSD is triggered. Due to the fact that the size of the RBDT is very small, the size of the RBDT can be remarkablyreduced. In order to reduce the energy loss of the pulse power generation circuit, when the RSD is triggered, the inductor is used for storing energy released by the capacitor when the RSD is triggered, and finally, the inductor is used for releasing the stored energy to form a load current pulse.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and more specifically relates to a pulse power generating circuit composed of solid-state switching devices. Background technique [0002] Pulse power technology refers to the electrophysical technology that stores the stored energy for a relatively long period of time, and then releases the stored energy to the load in a short period of time through the switching device to generate high-power electric pulses. Nuclear physics technology, sewage purification and other fields are widely used; the energy storage methods of pulse power generation circuits in the prior art are mostly capacitor energy storage and inductive energy storage, and traditional spark gap switches, pseudo-spark switches and triggers are mostly used. The vacuum switch acts as a discharge switch. During the continuous turn-off of the switch, the switch must have a very high turn-off frequency, an extremely short reverse rec...
