High-accuracy core loss models are an essential foundation for loss evaluation and efficiency optimization in servo power converters. A PWM excitation core loss model is proposed based on the DC power method to address the issue of large errors in core loss evaluation under PWM excitation using the Modified Steinmetz Equation (MSE) in traditional methods. This method directly establishes a loss model based on the measurement results of magnetic core loss under PWM excitation obtained by the DC power method, which can avoid the errors introduced by the MSE model in the waveform equivalent transformation stage and has better model accuracy. The experimental results show that the maximum relative error of the proposed model for loss evaluation under different excitation waveforms, frequencies, duty cycles, peak AC magnetic flux densities, and temperatures is -5.029%. The average absolute value of the relative error is only 1.72%, much lower than the model error of MSE (maximum relative error: 87.663%, average absolute value of relative error: 38.04%). It verifies the accuracy of the PWM excitation core loss model proposed under a wide range of operating conditions and can provide a high-precision calculation model for loss evaluation of power converter magnetic components under PWM excitation.
