About the project

Basis for the four MoWiLife pilots is a 2.3 kV SiC MOSFET, which will be developed by project partner Infineon. It includes a source-gate PiN diode, whose on-state voltage has a strong temperature dependence and can be read out by the gate drive, which will be developed by Rostock University. In addition, self-protection features will be integrated into the SiC chip for robustness and direct water cooling will be realized for higher output power.

Two wind energy converter pilots are being realized in MoWiLife by two industrial partners.

Work Plan

Work Package 1

Work package 1 lays the basics for the other work packages. This concerns the target specification for the SiC MOSFET module, the interface definition for the drivers used in several work packages, the condition monitoring concepts and the test scenarios.

Work Package 2

In WP 2, a 2.3kV SiC MOSFET XHPTM module with high power density, self protection features and access to TSEP is researched. For this, special features for robustness and reliability increase are implemented and tested.

Work Package 3

Realization of a level 2.5 MW SiC based power stack for use in wind turbines. Realized stack will demonstrate 20 % higher power density than existing Si based state-of-art stack.

Work Package 4

Realization of a SiC power Stack with junction temperature measurement. Online state-of health monitoring. Test of the implemented onlinemonitoring with a powercycling test.

Work Package 5

Demonstration of a medium-voltage DC-DC converter with an output voltage of 10 kV for large photovoltaic generation facilities. A very high efficiency with a switching frequency around 50 kHz is aimed for.

Work Package 6

In WP 6, we will evaluate the use of SiC MOSFETS in the High-Voltage hybrid DC Circuit Breaker. This will include a scaled hardware demonstrator

Work Package 7

Investigation of the possibility of using Ultra-Wide Bandgap material for high breakdown voltage, thereby overcoming the limitation of silicon carbide devices

Work Package 8

Develop and execute a Strategy for the communication, dissemination and exploitation of the key results in the previous WP. The strategy aims to maximize the impact of MoWiLife on Society and relevant Stakeholders.

Work Package 9

In WP 9 all project management tasks are summarized. This includes the installation of an efficient communication platform and support for the exchange of experience between the partners, monitoring of the workflow,
