摘要：

This article investigates the loss measurement methods of magnetic components for power conversion applications. A comparison calorimetric method is proposed for magnetic component loss measurement, and the proposed method can eliminate measurement errors of the traditional calorimetric method. The measurement principle is introduced in detail and this method is realized, and possible sources of error in measurement are evaluated and addressed. Hysteresis control is utilized to achieve automated measurement. Resistor and air-core inductor are used to verify the accuracy of the proposed method. The results show that the proposed method can be used to measure the loss of resistor and inductive element for high frequency up to 5 MHz, and the range of loss is 0.1-10 W.
