Inverter Integration Strategy for Traction Drives with Highest Power Densitiy based on SiC

Abstract

In a short time, electromobility will dominate the road traffic in industrialized countries, either as a battery electric vehicle (BEV) or as a fuel cell vehicle with electric powertrain (FCEV). The traction inverters used in this new vehicle types have the demand for low cost, high power density and high efficiency. In order to achieve a high level of integration, different packaging strategies, technologies and design approaches are summarized in this paper.
