Influence of power semiconductor on-voltage on iron loss of inverter-fed

Abstract

The influence of power semiconductor on-voltage on iron loss of inverter-fed electrical steels is made clear through the experimental data. One-phase full bridge inverter is used for an iron loss evaluation, where Bipolar transistor, MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and IGBT (Insulated Gate Bipolar Transistor) are selected as power semiconductors in an inverter circuit. When maximum magnetic flux density is adjusted to be 1 [T] in the electrical steel, the measured iron loss is different from the three kinds of power semiconductors.
