“…These devices have successfully been applied in many power electronics applications, in which they can provide additional control parameters to optimise the converter operation. For instance, they have been used as an additional strategy to control output power in electronic ballast applications [2][3][4][5][6][7]; to provide constant frequency operation in DC-DC resonant converters [8]; to optimise core size in bidirectional DC-DC converters [9]; to improve switching behaviour in DC-DC converters [10]; to provide an independent method to control the current through different LED arrays in a one-stage converter [11,12]; to optimise the operation of power factor correction (PFC) converters [13,14]; and to improve regulation and voltage gain in DC-DC converters [15].…”

In this paper, the analysis of the quad-U variable inductor (VI) is presented. This is an alternative structure of VI to other ones previously presented and analyzed in the literature, as for example the double-E structure and the triple-E structure. Compared to them, the quad-U structure shows some advantages, namely more symmetrical operation and zero voltage reflected across the bias winding. The superposition law is applied to the equivalent reluctance model in order to solve for DC and AC operation separately. Using the proposed methodology, both AC winding inductance and DC winding inductance can be obtained. An example of analysis is presented for a particular quad-U VI. Simulation and experimental results prove the validity of the proposed analysis and modeling methodology.

“…Variable inductors (VIs) and variable transformers have been used in a variety of applications [20][21][22][23][24]. In [22], a linear VI with double toroid configuration is presented without coupling between the AC winding and the DC winding, and similar designs are applied in [23,24] for high-frequency applications.…”

This study presents a new coupled inductor magnetic structure with variable coupling coefficient. The new symmetrical magnetic structure is composed of stacked ferrite cores, where control legs are placed in the centre of the core structure, on equal distances from the outer legs. In that way, the coupling coefficient is controlled by the means of a DC current. The DC control flux is confined only to the control legs and it is equally balanced in both of the outer legs. Distribution of the control DC flux in the proposed structure is verified applying finite element analysis simulation of the three-dimensional model. Electrical properties of the new variable coupled inductor are derived applying analytical modelling and verified by experiments. Maximal variations of the controlled coupling coefficient value in respect to the different value of the leakage flux are obtained and presented. Design and experimental results are presented for application in an interleaved boost converter with a variable coupled inductor, achieving boundary conduction mode over a wide load variation.
