Abstract The measurement error of core loss by AC meter will be very large especially when the impedance angle of magnetic component is closed to 90°. So a new DC meter method is proposed in this paper. The basic idea is to transform the input DC voltage into a square waveform on the magnetic component by a DC-AC inverter, and obtained the core loss by measuring the input active power. The method could avoid the influence of impedance angle to the measurement accuracy. However, with this method, the losses excepting for core loss should be excluded someway. A method of calibration with air core inductor is proposed to effectively calculate and take out the losses except core loss. The experimental results verify that the DC meter method is accurate to measure the core loss of low loss angle magnetic component.
