New semiconductor technologies, like SiC, are being integrated into electric vehicles (EVs). These semiconductors reduce losses to improve the driving range of EVs, and higher switching frequencies minimize harmonic losses. This work presents a framework to quickly assess different topologies and semiconductor technologies where both two- and three-level converters are scrutinized.
The design expressions of an indirect matrix converter (IMC) and a Δ-Switch IMC are discussed in this work based on the specifications of a 10 kW motor drive system with 1.2 kV SiC power semiconductor devices. The conduction and switching losses models for both topologies are presented to be used in the dimensioning. The ΔIMC leads to a peak efficiency of 97.7% at a switching frequency of 20 kHz with...
To reduce the conduction loss, a novel three-phase current source rectifier, named Delta-type Current Source Rectifier (DCSR), has been proposed in previous paper. This rectifier has delta-type connection on its input side, and its dc-link current can be shared by multiple devices at a time to reduce up to 20% conduction loss. The SiC devices are expected to be the next-generation power devices due...
