摘　　要：分析了交流测量法测量磁心损耗误差较大的原因，采用直流测量法间接测量磁心损耗并设计制做了损耗测量装置。该装置能方便、快速测量方波激励下的磁心损耗，为用户设计高性价比的磁性元件提供依据。This paper first analyses why the Magnetics loss measurement system test core loss under rectangular reliable reference for the design measurement error of the AC method is unacceptable, A set of based on DC method is designed and established. The system can waveforms conveniently and rapidly. This system can provide of magnetic components
