Abstract :
Conventional and new techniques for making high-frequency B versus H loop and core-loss measurements on magnetic cores are presented and compared. Potential sources of measurement errors and their magnitudes are discussed along with circuits suitable for high-frequency sine-wave or square-wave core excitation. The utility of such measurements is illustrated with sample data.
