Magnetizing Current of Transformer is usually Provided to Load

Currents of transformer consist of load current and magnetizing current. It is believed that magnetizing current flows only in primary winding and is not provided to load. It is correct for ordinary transformers but not for transformers of DC/DC converters. In this paper, many examples in which magnetizing currents flow in secondary winding and provided to load are described. キーワード:DC/DC コンバータ、励磁電流、高周波トランス
