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.

Agreed, not an efficient way to store energy. I we think about we use inductors to store energy, often for only microseconds. Yes, just like caps, even the use in simple pi filters on AC driven power supplies uses the inductor to store energy and give it back when there is a voltage drop (many times per second).
When a electric current is flowing in an inductor, there is energy stored in the magnetic field. Considering a pure inductor L, the instantaneous power which must be supplied to

An inductor is, therefore, characterized by its time constant (τ = tau), which is determined using the formula: τ = L R τ = L R. where. τ = time constant in seconds. L = inductance in henrys. R = resistance in ohms. This expression shows that a greater inductance and a lower resistance will cause a longer time constant.
When you apply a constant voltage across an inductor for a short period of time, current ramps up from zero amps to some value.
The energy stored in the leakage inductance is typically dissipated in a snubber network and, therefore, decreases efficiency. Hence, it''s vital the leakage inductance be as small as possible. Volt-second

The success of such an energy storage system depends entirely on the resistances present, and not on what voltage you use to "charge up" the store. In fact, since the idea is to establish a "semi-permanent" current in the loop, it doesn''t make sense to talk of reducing current there.
By forcing a zero algebraic variation of the volt-second product, all solutions can keep the volt-second balance of the power inductor so that no risk of magnetic saturation in the
The energy stored in the magnetic field of an inductor can be written as: [begin{matrix}w=frac{1}{2}L{{i}^{2}} & {} & left( 2 right) end{matrix}] Where w is the stored energy in joules, L is the inductance in Henrys,
