Description
Summary:The authors propose a core loss calculation method for power electronics converter excitation from sinusoidal excited core loss data. This method is based on Brockmeyer’s theory and adapts to calculate core loss under DC-bias excitation conditions. Furthermore, the number of core loss test conditions are reduced as this method only requires the addition of DC-bias characteristics to the sinusoidal excitation core loss data provided by the core manufacturers. To validate the proposed method, the core losses under sinusoidal and square voltage excitations are first measured by a BH analyzer with a DC-bias excitation unit. Then, the measured values under a square voltage excitation and the calculated values from a sinusoidal excited core loss data are compared.
