“…It must be pointed out that the self-inductances of the integrated inductor windings in the matrix are the leakage inductances we intend to find due to the very good decoupling and the very small mutual inductances. Taking as a reference the calculation for leakage inductance of the interleaved core-type transformer winding [14] [15], the inductance of the integrated filter inductor winding could be estimated, which is the second method. However, it is highly recommended that both of the two mentioned methods are used because of the complicated magnetic effects and multiple-variable dependent computation, attempting to get the results correct relatively.…”

A new method for harmonic suppression and reactive power compensation which is integrated with converter transformer is proposed to deal with the oversize problems of transformer and harmonic filter system in the cases where physical space is of limit. Based on the presented non-orthogonal decoupling mechanism, the integrated filter is designed and constructed. In this paper studies are performed on the decoupling effect, the inductor winding linearity and inductance computation, and the harmonic reduction and reactive power compensation performance of the described integrated filter. Simulation and experimental verifications of an integration converter transformer prototype are provided.Index Terms-integrated filter, non-orthogonal decoupling, converter transformer, harmonic suppression and compensation

“…In the literature, many methods have been reported to assess the leakage inductance of a transformer, based on Finite Element Analysis (FEA) or analytical calculation [21]- [35]. For FEA, computation can be made in 2D, 3D, or mixed 2D/3D for HF losses and inductance values [1], [21]- [23]. FEA is a powerful tool to study electromagnetic components but when dealing with optimization, using such tool can be very cumbersome and time consuming.…”

Planar magnetic components are promising solutions for the integration of power electronic systems. The leakage inductance of such components plays an essential role in power converters. In this paper, an analytical modeling method for leakage inductance computation is developped for planar components with plasto-ferrite leakage layers. This method is based on the solution of Poisson's equations for magneto-static using multilayered Green's functions. The obtained formulations are general and precise and have been validated by numerical tests. Experimental characterizations have been performed on two magnetic components: A planar LLC and planar common mode choke. The obtained results show that with the described method, the static leakage inductance of planar components can be accurately estimated.

“…Calculation of equivalent leakage inductance L eq To calculate the equivalent leakage inductance L eq , it is necessary to firstly calculate the equivalent leakage inductance of secondary winding L s_eq . L s_eq is mainly correlated with the number of turns N s12 , the average turn length of secondary windings l a , core window width along x axis b w and core window height h w [17,21,22]. The formula is shown below.…”

A novel zero voltage switching (ZVS) phase shift full bridge (PSFB) converter used in geophysical exploration is proposed in this paper. To extend the ZVS ranges and increase power density of the converter, external inductor acting as leakage inductance is applied and integrated into the integrated magnetic (IM) transformer with separated secondary winding. Moreover, the loss of ZVS PSFB converter is also decreased. Besides, the analysis and accurate prediction methodology of the leakage inductance of the IM transformer are proposed, which are based on magnetic energy and Lebedev. Finally, to verify the accuracy of analysis and methodology, the experimental and finite element analysis (FEA) results of IM transformer and 40 kW converter prototypes are given.
