Active rectification of the three-phase grid nowadays is a central task of power electronics. However, as the necessary DC bus voltages vary, DC-DC converters are needed. This study presents the design and development of a three-phase power factor correction with an interleaved buck converter in the output stage. The power stage switches are equipped with silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors. A modular setup of the half-bridge modules as well as low inductive design of these modules is put into focus.
