Performance model of vacuum arc thruster with inductive energy storage

Inductive Energy Storage Circuits and Switches | SpringerLink
Abstract. The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch. Prior to this action, of course, the opening switch must first conduct the current as required--that is, operate as a closing switch. To accomplish current interruption, the opening switch must force the current to

How to Measure Inductance?
The most common way to calculate inductance is by using the formula L = (μ x N2 x A) / l, where μ is the permeability of free space, N is the number of turns in the coil, A is the cross-sectional area of the coil and l is the length. You can also measure it directly using an inductance meter or an oscilloscope.

Energy Stored in an Inductor | Electrical Academia
Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up

It''s merely impractical for many of the alternating current (AC) components we work on. That''s because the ohms we measure don''t account for all resistance types that make up total impedance.
