Abstract
This paper presents a novel modulation scheme
that enables the implementation of a hard-switched T-type
converter using silicon Superjunction MOSFETs in the Tbranch.
Compared to a conventional 2-Level IGBT converter,
the proposed approach significantly reduces both conduction
and switching losses while maintaining a cost-effective design.
The converter is fully silicon-based, offering substantial cost
advantages over wide-bandgap alternatives. A modified switching
strategy is introduced to enable the reliable operation
of Superjunction MOSFETs under hard-switching conditions.
Simulation results demonstrate high efficiency across the entire
load range in AC-DC operation, with particularly strong
performance under partial load. Experimental validation is
carried out on a three-phase AC-DC converter prototype
operating with a passive load, confirming the functionality
of the proposed switching scheme. This work highlights the
potential of silicon Superjunction devices for high-efficiency,
three-phase industrial power conversion and presents a viable
alternative to more expensive wide-bandgap-based solutions.
