  • Modelling and optimisation of planar matrix transformer for high . . .
    By pushing switching frequency up to megahertz with Gallium Nitride (GaN) devices, a planar transformer with PCB winding can be adopted to achieve high power density and low profile [] Fundamental properties and issues of LLC converters with planar transformers have been reviewed in [11-13] For optimal design of the planar matrix transformer, it is decisive for the efficiency and power density
  • Optimization Design of Magnetic Integrated Planar Transformer for . . .
    For the traditional transformer design cases, the AP method is commonly employed for selecting core types The total loss of a high-frequency planar transformer is composed of core losses and winding losses The core losses are related to the core material, core shape, and magnetic flux density Ouyang Z, Thomsen OC, Andersen MAE (2010
  • Design of high frequency (MHz) planar pot-core transformer
    High-frequency planar transformers are widely used in many electronics converters, such as inverters, drives, power supplies, and resonant converters The design process of the high-frequency planar transformer is very complicated because of high-frequency interaction between the windings due to which numerous problems persist, namely: (a) leakage inductance, (b) skin and proximity effect, and
