Abstract:The basic idea of the DC meter method was to transform the input DC voltage into a PWM voltage exciting on the magnetic core by a DC/AC circuit,and the magnetic core losses were obtained by measuring the active power of input DC voltage.The DC meter method could measure the magnetic element losses under the rectangular wave excitation accurately.In order to separate the copper loss from the core loss,the air-core inductor was introduced as load.The experimental system was build at last,the measurement results were compared with the results which were calculated by Fourier transform,the maximum relatively error was 12.91%.The verification test was build to validate that the novel measurement method is accurate enough for practical applications.
