| Popis: | Two operating modes have been identified for a matrix inductor/transformer made by weaving conductors through the holes perforated in a flat magnetic plate. The Mode-1 perforated-plate matrix transformer (M1PPMT) is analyzed to assess its suitability for low-profile power converters. Analysis and finite-element simulation suggest 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 100 W M1PPMT with acceptable magnetizing inductance, efficiency, and power density. > |
