摘　　要：研制出频率范围 5 0Hz～ 5 0kHz的动态磁性能测量仪样机 ,该仪器是基于 16位微处理器的便携式仪器 ,包含信号源、功率放大器、电压表、电流表和功率表。采用准同步采样方法和数值积分算法 ,计算磁滞回线和损耗、磁导率等参数。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.
