摘要：

A practical method to measure transformer core loss in a high-frequency switching mode power converter is proposed. The method is also applicable when the transformer has dc bias in the magnetizing current. Practical issues to minimize the measurement error are discussed. The measurement results are very close to simulation results obtained from a time-domain finite element analysis solver. Detailed error analysis for the proposed method provides useful guidelines on transformer core loss measurement for switching mode power supplies.
