Abstract

Adhering to the objective of modelling and selecting the most optimal winding configuration for a high frequency planar transformer (HFPT) for auxiliary charging systems for more electric aircrafts (MEA) this disclosure elucidates numerous fabrication and design-based constraints and correlations to enable parametric modelling of various magnetic components. This disclosure characterizes possible winding configurations for HFPT employed in a bidirectional CUE DC/DC converter. A detailed analytical study is presented for each component and verified using several instances of 3D Finite Element Analysis (FEA) based model to synthesize the effective field and current density distribution in the windings. Several design-based trade-offs are graphically explained with various criteria pertaining to optimal winding selection to study the interdependence of the resultant parameters on hardware specifications, such as the PCB thickness and its fabrication layout, air gaps and conductor thickness.
