11:00 Effects of a SiC TMOSFET Tractions Inverters on the Electric Vehicle Drivetrain
Dipl.-Phys. Alexander Nisch, Daimler, Sindelfingen, Deutschland
Due to the constantly increasing demand for the electrical range and to the restricted installation space, the request to the energy efficiency of a traction inverter will increase. Silicon carbide MOSFETs are considered as the most promising semiconductor devices for future traction inverter applications. In the presentation we discuss the potential and challenges of a three-phase voltage-source-inverter based on trench SiC MOSFET under automotive constraints, considering the complete drivetrain.
11:25 Highly Integrated Traction Inverter for a Modular Drive Concept
Dr.-Ing. Ulf Schümann, University of Applied Sciences Kiel, Kiel, Deutschland
The growing demand of electrification in automotive powertrains requires an adapted, efficient, compact and cost-effective drive topology depending on the vehicle class. In the context of a research project, a novel design for an integrated traction inverter is developed which provides a scalable modular drive train. The paper gives a closer look to the integration approach by describing the development of the inverter components, aiming to reach a power density of 100kW/l.
11:50 Automotive Traction Inverter Utilizing SiC Power Module
M.Eng. Masaharu Nakanishi, ROHM Semiconductor, Willich, Deutschland
In recent years, the market expansion of Silicon Carbide (SiC) power transistors has been started. We have seen a lot of improvements such as higher efficiency circuit and system miniaturization. EV/HEV/PHEV application has variety of usage for SiC Power devices. This paper focuses on to describe the benefits of newly developed high current/low stray inductance SiC Power Module and the optimizations of its SiC power module utilized traction inverter by comparing with conventional technology based traction inverter performance.
12:15 Novel Approach of Integrated Motor-Inverter Power Module for 48V Mild Hybrid Starter and Generator (MHSG)
B.Eng. Jihwan Seong, Hanyang University, Seoul, Südkorea
This paper newly presents power-module design aiming to integrate a motor and inverter in a single package. The integrated motor-inverter concept is specialized for a 48V mild hybrid starter and generator (MHSG) system in vehicle. This DBC-based integration reduces system size/volume, system parasitic inductance/resistance, and thermal resistance. These advantages are validated by using multi-physics finite element method (FEM) simulations, and experiments, exhibiting notable decreases in system inductance and peak voltage
