Abstract
Increasing the switching frequency of direct current–direct current converters is effective in reducing the size of magnetic components used in converters. However, as the switching frequency increases, the loss and heat generated by the magnetic components increase. Therefore, in this study, a magnetic tape that bypasses the magnetic flux in the windings of magnetic components is proposed to reduce the loss and heat generation of these components. The effect of suppressing the temperature rise of magnetic components with a magnetic tape during the converter drive was investigated. The temperature rise of a 1-MHz 100-V/200-V 800-W boost inductor was reduced by 16.8 K by applying the magnetic tape. Additionally, applying the magnetic tape to the inductor reduced the heat generation.
