GENERAL CONTEXT
SiC MOSFETs have revolutionized power energy conversion above 600 V with their lower on-state resistance and higher switching frequency compared to Silicon IGBTs. Their maturity is growing strong, and manufacturers are integrating this technology ever more. Nonetheless, condition and health monitoring of these “new” devices is required to fully exploit their potential in power conversion. This research field is thus gaining momentum and is pushing both academia and industry to seek solutions for electrical parameter online measurement and remaining useful life estimation. Electrical parameter measurement is the first step towards condition & health monitoring but is a challenging task as it has to be carried out during the operation of the converter in most cases. On-line measurement of SiC MOSFETs’ electrical parameters is thus the goal of this internship.
Benefits :
* Remboursement des transports à 50%
OBJECTIVES / MISSIONS
The goal of the internship is to perform the accurate measurement of electrical and thermals SiC MOSFETs parameters and build an electrothermal modelling platform. The second, but main goal is to implement on-line electrical parameter monitoring system on SiC MOSFETs.
TASKS:
* Literature review
* Electro thermal characterisation of SiC MOSFET (650 V to 3.3 kV)
* Electrothermal modeling of SiC MOSFETs on LTspice
* Prototyping measurement
* Drain Source voltage
* On-state resistance
* Junction temperature
