Abstract :
A very versatile experimental method for measuring losses in magnetic components is presented. This is not subject to the bandwidth constraints associated with the direct wattmeter method. The proposed method features accurate measurement of conduction losses, separation of core and conduction losses, measurement at high frequencies, and scale modeling of magnetic components. The experimental measurements are compared with theoretical predictions of components as applicable to certain power electronic converters
