Design of a full SiC three‐phase power factor correction with an interleaved output buck converter

Abstract

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.
