Abstract

The perforated-plate matrix power transformer is analyzed to assess its suitability for low-profile applications. Finite-element simulation suggests that this type of transformer may be approximated as a collection of weakly coupled toroidal cores. Thus, it is possible to derive closed-form expressions relating typical performance parameters, such as magnetizing inductance and losses, to the hole radius, identified as a meaningful design parameter. High peak flux density around the holes appears to be a problem. Nevertheless, it is possible to design a perforated-plate matrix transformer with acceptable magnetizing inductance, efficiency, and power density
