The size of an inductance is expressed in Henrys (after Joseph Henry, an American contemporary of Faraday). A large choke may have an inductance of 10H or more, whilst that of a small coil may be 100μH or even less. A piece of wire has an inductance of about 25nH per inch (or 1μH/m). There''s a more exact formula

The first is the coil''s size and geometry, which dictate the coil''s inductance. Clearly, the bigger the coil, the more energy is contained. The second element is the conductor properties, which are responsible for determining the maximum current. Superconductors are capable of carrying large currents under strong magnetic fields. To keep the ...
In principle, the operation capacity of the proposed device is determined by the two main components, namely the permanent magnet and the superconductor coil. The maximum capacity of the energy storage is (1) E max = 1 2 L I c 2, where L and Ic are the inductance and critical current of the superconductor coil respectively.
Energy in an Inductor. 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 initiate the current in the inductor is . so the energy input to build to a final current i is given by the integral. Using the example of a solenoid, an expression for the energy density …
Determinants of Energy Storage in Inductors The energy storage capacity of an inductor is influenced by several factors. Primarily, the inductance is directly proportional to the energy stored; a higher inductance means a greater capacity for energy storage. The current is equally significant, with the energy stored increasing with the square ...

Whether HTSC or LTSC systems are more economical depends because there are other major components determining the cost of SMES: Conductor consisting of superconductor and copper stabilizer and cold support are major costs in themselves. They must be judged with the overall efficiency and cost of the device. Other components, such as vacuum vessel insulation, has been shown to be a small part compared to the large coil cost. The combined costs of conductors, str…

Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.

This is further demonstrated by the time constant of a coil, t = L/R, where L is the inductance and R is the resistance. When R tends to zero, t approaches infinity. The operation of SMES is based on the notion that a current will continue to flow in a superconductor even after the voltage across it is eliminated [8]. A superconducting coil with minimal (zero) resistance is …

But somehow it helps reduce inductor size (and energy too)! Mathematically it is simple to explain. The "culprit" is the odd term involving current ripple ratio r in the ε PEAK equation above. We isolate that term below. ε PEAK = Δ ε 8 × F (r) where. F (r) = [r × (2 r + 1) 2] If r is very small, 2/r is >>1. So, F (r) ≈ [r × (2 r) 2] = 4 r. We see that the F(r) function imparts an ...
