In this paper, the analysis of parasitic effects of a non-overlapping interleaved planar transformer structure is presented using finite element modelling. The major parasitic effects seen in planar transformers are leakage inductances and stray capacitances between their windings. In this work, a non-overlapping interleaved planar transformer wind...
In this work, fringing effect is studied on planar transformers for various frequencies, air gap lengths, core materials and core geometries to aid engineers in choosing the best transformer design with least fringing losses. Using finite element modelling, fringing losses were analysed for four different core geometries, namely EE, EI, ER and ETD,...
In this paper, the finite element electrical, thermal and electro-magnetic analysis of an interleaved power electronic transformer structure operable at 100 kHz is presented. The analysed power electronic transformer structure is modelled with an EE-shaped core and interleaved primary and secondary windings. Electromagnetic analysis was done on the...
In this work, various emerging core and winding materials suitable for a high frequency planar transformer (PT) has been analyzed and compared. Core and winding materials used in a transformer has a significant effect mostly in the core and winding losses of the transformer. Emerging core materials like amorphous and nanocrystalline cores were comp...
In this paper, a new topology for an isolated DC-DC converter that can be used for electric vehicle applications is presented in a dual bridge structure, having just one switch, two capacitors, and an inductor each in the front-end and back-end H-bridges, along with a high-frequency transformer (HFT) for isolation of the bridges. Simulations were d...
This paper presents a transformer-based multilevel inverter (MLI) topology, which reduces the overall cost of the system with lesser number of components than a conventional MLI. In this paper, a nine level MLI is designed which uses only eight switches, whereas a conventional transformer-less MLI requires 16 switches for achieving a nine-level vol...
