Abstract :
The volume and weight of a power conversion circuit depend considerably on magnetic components. Air-core reactor which can avoid core loss is suitable for power converters operating fast and high-frequency switching of the high voltage and large current. This study presents a compact model for the calculation of winding AC resistance of air-core solenoids, which includes the influence of skin and proximity effects, and verifies the adequacy of this model in the high-frequency region on the basis of the measured frequency characteristics of the impedance. This study also considers the optimal design dimensions of a single-layer solenoid to minimize copper loss for a given wire diameter and inductance value.
