摘要：

We have performed measurement of core losses in metal composite toroidal cores over 10 MHz region using a measurement system where capacitors are connected in series with coils wound around sample cores and the measurement is conducted at LC resonant frequencies. In this paper, we introduce this “Resonant Method” and show the core loss measurement of metal composite toroidal cores up to 40 MHz. Furthermore, we examine the accuracy of the Resonant Method by comparing the equivalent resistance evaluated from the energy loss and the real part of the impedance measured by network analyzer. © 2023 Institute of Electrical Engineers of Japan.
