“…The optimization of the inductor has been carried out using a finite-element analysis (FEA) tool, namely, Maxwell 2-D. This tool has been used in [17] to extract a model of the magnetic component and in [18] to improve the connection of paralleled wires. In this case, the simulation is simpler, since it is a winding with no core and with axisymmetric shape.…”

Abstract-A power electronics circuit allows the generation of high-frequency magnetic field that can be used to increase the temperature of cancer cells previously invaded with the magnetic nanoparticles. The circuit designed for this purpose is a high-frequency phase-shift inverter implemented with SiC devices and natural zero voltage switching. The inductive load has been optimized to increase as much as possible the magnetic field at the center of it considering the physical restrictions. Into this inductor, an adiabatic probe filled with nanoparticles is placed being the main objective to increase its temperature. The control of the inverter has been designed in such a way that it is easy to try waveforms different from the classical sine waves to see its effect on the temperature of the sample. Although the research is in one of the early stages, the first conclusions about the optimal frequency and field have been obtained showing that this technique could be a real option in the future.

“…One established strategy for predicting current behavior is to extract circuit parameters from the physical structure of the magnetic components, then use a circuit simulator (such as SPICE) to solve [8], [11]- [13]. Predictions of current distribution have been done based on Maxwell's equations, but their general application involves the solution of coupled differential equations which again introduces intuitive and computational barriers [14], [15].…”

In both planar and wire-wound transformers, large copper cross-sections and parallel windings are often used to increase conduction area and decrease copper loss. However, at high frequency, current is not guaranteed to spread out maximally over the cross-section of a single conductor or to split evenly between parallel conductors. Finite element analysis (FEA) and SPICE-based systems have been used to analyze current distribution within magnetic components, but these methods are computationally intensive. In this paper, we show that Maxwell's equations, in the high frequency limit, yield a set of linear algebraic equations that are rapidly solvable to yield both the current and magnetic field distribution and hence can be used to predict loss and leakage inductance. Due to its simplicity, this method is easily applied to cases with a one-dimensional or two-dimensional distribution of current. We show that predicted results match both FEA simulations and experimental measurements very accurately for a variety of cases. This paper is accompanied by several software implementations of the method. This method can be used to rapidly analyze high frequency current distribution in transformers and can easily be integrated into numerical optimization algorithms.

Abstract-Transformers with parallel windings are commonly used to reduce the losses in the windings. Windings losses depend on the winding positioning and the frequency effects because each winding affects the current sharing of itself and the neighboring windings.In this paper a methodology for determining the connections of the parallel windings that reduces the power losses (and temperature) in the windings of multi-winding transformers is presented. Other applications of the method, such as balanced current sharing and voltage drop reduction are also explored.
