Pulsed gas discharge is an important means of generating low temperature plasma. Short pulses with fast frontier show superior performance in terms of increasing the active particle content, ionization coefficient and electron conversion rate due to its higher voltage rise rate. The common nanosecond pulse generator is based on capacitive energy storage.

Abstract: Superconducting magnetic energy storage (SMES) is one of the few direct electric energy storage systems. Its specific energy is limited by mechanical considerations to a moderate value (10 kJ/kg), but its specific power density can be high, with excellent energy transfer efficiency. This makes SMES promising for high-power
Inductance is the influence of an electric field on a ferrous material, and the corresponding influence of that ferrous magnetic field back onto a conductor. Inductors can be used to step voltage up and down in the case of a transformer. In a DC circuit, inductors act similarly to a standard conductor, with only a small amount of wire resistance.

How do inductors store and discharge energy? In an inductor, the energy is stored in the magnetic field when there is current through the coil.
