Abstract

The invention relates to an XRAM pulse generation circuit. A reverse switching dynistor (RSD) is selected as a master switch, is a novel high-power semiconductor closing switch and is high in through-current capability and small in current change rate and delay jitter. A fast recovery thyristor is selected as a primary switch to reduce energy loss in the process of current conversion, so that output efficiency is improved. The XRAM pulse generation circuit has the advantages that peak current, current change rate and output efficiency of output pulses can be improved. By current conversion technology, current conversion capability of a unit inductance energy-storage system can reach tens of kA, the unit inductance energy-storage system is matched with a high energy-storage density battery or a small flywheel generator, a lot of inductance energy-storage units are in parallel-connection running, and a high-power pulse power source system with energy storage from hundreds of kJ to several MJ can be realized.

Description

technical field [0001] The invention relates to an XRAM pulse generating circuit, which is mainly used in a pulse power system to generate low-voltage, high-current high-power pulses. Background technique [0002] Pulse power technology compresses energy on a time scale to obtain high power pulses. The traditional Marx circuit uses multiple capacitors to be charged in parallel by a voltage source and discharged in series by closing a switch to realize voltage superposition and power amplification. The XRAM circuit uses multiple inductors to be charged in series by a current source, and is discharged in parallel through a circuit breaker to realize current superposition and power amplification. Compared with the capacitor energy storage method, the energy storage density of the inductor is an order of magnitude higher. In addition, the inductor can generate a large current at a very low voltage, thereby greatly reducing the requirements for the primary power supply. Inducto...
