“…By using accurate analytical methods, time-consuming FEM simulations can be avoided in the design stage. Several methods for the calculation of the leakage inductance of a transformer can be found in the literature [36][37][38][39][40]. In the classical method for calculation of leakage inductance the effect of the core is neglected, and it is also difficult to consider asymmetries in distributions of ampere-turns.…”

“…To achieve this goal, the bulky 50/60 Hz transformers have been replaced with high power density DC-DC converters consisting of high-frequency transformers with lower weights and volumes. However, being exposed to higher frequencies, one should cope with extra losses coming from eddy current losses in the magnetic core [3], [4], excess losses in the windings due to enhanced skin and proximity effects [5], as well as parasitic elements, i.e., leakage inductance [6]- [8] and winding capacitance [9], [10], causing excess switching losses in the power semiconductors which is usually dominant at higher frequencies [11].…”

Moving towards higher power density in magnetic components, which is often realized by increasing the operating frequency, leads to the need for development of more accurate design tools, for example more accurate expressions for core losses, winding losses and leakage inductance calculations. This paper presents a new analytical expression intended to accurately evaluate the leakage inductance of transformers in the high frequency range in which the behavior of the magnetic field within the windings is altered. Unlike conventional expressions, which usually overestimate the leakage inductance at higher frequencies, this expression accounts for high frequency behavior of the magnetic field and provides high accuracy when operating at high frequencies. These high accuracy and applicability makes the derived expression of interest for designers to avoid time consuming finite element simulations without compromising with accuracy. The expression is validated by 2-D FEM simulation, as well as by measurements.

“…Compared with traditional transformers, chip magnetic components can work at higher working frequency due to the use of new magnetic materials. The planar magnetic core structure reduces the component volume height, limits the eddy current loss of the magnetic core to a certain extent, greatly increases the heat dissipation area of the magnetic core and winding, and improves the overall heat dissipation capacity [5][6][7][8][9][10].…”

With the rapid progress of power electronics high frequency conversion technology, the traditional magnetic components are more and more difficult to meet the requirements of modern electrical product design. In contrast, chip magnetic components have the advantages of small volume, low height and light weight in structure, small leakage inductance, low electromagnetic interference and high efficiency in electrical characteristics. They are very attractive in switching power supply with high frequency and high-power density. This paper studies the design and analysis of components, which has done useful work for the development of component magnetic design.
