An accurate characterization method of passive components for Very High Frequency power conversion applications
Une méthode de caractérisation précise de composants passifs pour des applications de conversion d'énergie à très haute fréquence
Résumé
The successful design of Very High Frequency (VHF) power converters depends on the accuracy of passive components models. In this work, a 30 MHz 40 W class E inverter is simulated to emphasize the impact of the fabrication tolerance of the resonant passive components. A multi-layer ceramic capacitor (68 pF), two air-core inductors (22 nH and 360 nH), and a thick film surface-mounted resistor (1 Ω) are accurately characterized in the VHF range. The characterization method and the de-embedding process are thoroughly explained. Extracted model parameters are compared to the model specified by the manufacturer. The impact of the ground plane located under the air-core inductor on its impedance is evaluated in 2-port shunt-through configuration.
