LTspice will faithfully model both ideal and real magnetic devices. However, caution is advised when first experimenting with unfamiliar concepts in inductors and transformers. Be sure to minimize simulation problems by including reasonably realistic parasitic resistances (both series and parallel) directly into each inductor, whether used ...
A single-magnetic bidirectional integrated equalizer using the multi-winding transformer and voltage multiplier for the hybrid energy storage system is proposed. The multi-winding transformer and voltage multiplier, driven by the current ripple of the inductor in the bidirectional buck-boost converter, are used for the battery string …

The footprint area of a three-cell inductor is 1.48 times less than that of the conventional toroidal inductor with same energy, maximum flux density, material properties, winding loss, and core loss.
Homopolar inductor machine (HIM) has caught much attention in the field of flywheel energy storage system (FESS) due to its merits of robust rotor, brushless exciting, and high reliability. Compared with permanent magnet HIM (PM-HIM), the HIM with field winding (FW-HIM) can effectively eliminate the idling loss caused by the no-load …
This paper presents a review of the proposed cell balancing topologies for BESSs. Comparison among the topologies is performed for four categories: balancing speed, charge/discharge capability, main elements required to balance n cell, and application types. Keywords Battery Energy storage Cell balancing Active Passive.
In an inductor, the core provides the flux linkage path between the circuit winding and a non-magnetic gap, physically in series with the core. Virtually all of the energy is stored in the gap. High permeability fer-rites, or magnetic metal alloys such as Permalloy, are incapable of storing significant energy.

OR SWITCHING POWER SUPPLIESLloyd H. Dixon, JrThis design procedure applies to m. gnetic devices used primarily to store energy. This includes inductors used for filtering in Buck regulators and for energy storage in Boost circuits, and "flyback transformers" (actually inductors with multiple windings} which provide energy storage.
causes a specific amount of inductance decrease. This is usually the current that causes 10%, 20% or 30% inductance drop. Let''s examine a nominal 100 µH inductor (Coilcraft part number LPS3015-104) with 30% inductance drop Isat rating of 0.26 Amps.
In a weak energy environment, the output power of a miniature piezoelectric energy harvester is typically less than 10μW. Due to the weak diode current, the rectifier diode of traditional power management circuit in micro-power energy harvester has a high on-resistance and large power consumption, causing a low charging power. In this paper, an …

Constant-flux inductor with enclosed winding for high-density energy storage H. Cui and K.D.T. Ngo The ''constant-flux'' concept has been described in a recent Letter as a way to utilise space more efficiently for inductor geometry with the core enclosed by winding.
The ''constant-flux'' concept has been described in a recent Letter as a way to utilise space more efficiently for inductor geometry with the core enclosed by winding. While the concept can conceptually be extended to the companion case of the inductor with winding enclosed by the core, structural synthesis is complicated by the absence of circular symmetry.
