| Abstract |
This study investigates the inductance formulas for square-shaped planar windings and suggests modifications so they can apply to rectangle-shaped windings, with simple yet accurate approximations. Furthermore, it explores the region of high-power, high-frequency planar transformers, introducing an algorithm which estimates the applied voltage per turn. This effort can lead to design optimization, by minimizing the spacing between traces, thus increasing the inductance over used area. A comparison of theoretical, simulation and experimental results is carried out to evaluate three well-established formulas under the proposed modification. The voltage distribution algorithm is also verified using the same methods. |
