Abstract

The invention belongs to the technical field of electromagnetic emission, and provides a novel n-stage inductance energy storage type large current source circuit topological structure which comprisesa primary power supply, an n-stage inductance series charging and parallel discharging basic loop topological structure and an electromagnetic rail gun load structure. According to the novel inductance energy storage type large current source circuit structure provided by the invention, the thyristor is adopted as a switching device in a switching part, and reverse voltage is applied to the switching device through the reverse diode connected with the switching device in parallel, so that reliable turn-off of the thyristor can be realized, and the controllable performance of a system is effectively improved. An optimized backward diode is added to a control part in the topological structure of the circuit to fully isolate a charging loop, so that the linear rise of inductive current and the stability of capacitor voltage in the charging process are ensured. Ripples of the capacitor and the inductor are avoided, and the charging efficiency of the power supply is improved. Besides, then-stage inductance energy storage type large current source circuit topological structure provided by the circuit is relatively simple in structure and has relatively good expansion performance.
