【Abstract】 The measurement meter of magnetic materials’ dynamic characteristics has been developed, which is designed based on microprocessor technique. It covers a frequency range from 50Hz up to 50kHz. All components are integrated in the measurement meter, such as signal generator, power amplifier, voltage meter, current meter and power meter. Using quasi-synchronous sampling method and numeric integration algorithm, the measurement meter calculates hysteresis loop and characteristic values like core losses and permeability.更多还原
