Flux-controlled magnetic-core-loss tester has been developed that produces high-frequency core-loss data (within 2 percent) for any desired waveform excitation and allows magnetic characteristics of material to be measured under symmetrical and asymmetrical excitation conditions. It allows direct control of additional loss variable rather than just driving frequency as is case for all previous sinusoidal core-loss measurements.
