Abstract: A trans inductor having a powdery magnetic substance and a power converter using the trans inductor are provided. The trans inductor and the power converter reduce peak current flowing in an inverter power module (IGBT), improve inverter efficiency, reduce output RMS current (output effective current) and reduce capacitor consumption by applying a material with properties that are resistant against current saturation instead of a core material of a conventional trans inductor employed in a power converter. Accordingly, an inductance decreasing rate due to core saturation when high current is generated is improved and current flowing in a switch device is prevented from being abruptly increased.
