The core of lightweight and high-performance operation of electromagnetic propulsion and directional energy equipment lies in the improvement of pulse power system indicators

but the technical indicators of traditional capacitive energy storage and its pulse power conversion methods are approaching their limits. Inductive energy storage pulse modulation technology has broad application prospects in the field of pulse power supply due to its advantages of high energy storage density and fast energy release. This paper summarizes the basic principles

typical topology structures (superconducting transformer type

XRAM type

and Meat Grinder type)

and technical characteristics of inductive energy storage and pulse modulation technology. Comprehensive analysis shows that the combination of transformer topology with superconducting coil energy storage and XRAM scheme

as well as the introduction of Meat Grinder derived topology with inverse current commutation with semiconductor technology

is expected to become the mainstream technology route for high-power pulse power supply; however

it still faces technical challenges such as high power demand for primary power supply and difficulty in cut-off of high currents. The future development directions mainly include high-performance superconducting coils and their refrigeration technology

high-voltage switching devices

design of auxiliary converter circuits and coupling circuits

multi-type topology combination and parameter optimization

etc.

so as to promote the engineering application of inductive energy storage and support the performance improvement of electromagnetic propulsion and directional energy equipment.
