The influence of body effect and threshold voltage reduction on trench MOSFET body diode characteristics

Proceedings of the 16th International Symposium on Power Semiconductor Devices & IC's, 2004
This paper presents a comprehensive study of the body diode characteristics of high-channel density trench power MOSFETs using analytic modeling, 2-dimensional numerical simulation, and physical measurements. The results show that, for state-of-the-art trench MOSFETs, the body diode characteristics are strongly influenced by majority carriers in the ...

Telerobotic contact transscleral cyclophotocoagulation of the ciliary body with the diode laser

Journal of Robotic Surgery, 2013
To assess the feasibility of using the Robotic Slave Micromanipulator Unit (RSMU) to remotely photocoagulate the ciliary body for the treatment of glaucoma with the diode laser. In fresh unoperated enucleated human eyes, the ciliary body was destroyed either with a standard contact transscleral cyclophotocoagulation 'by hand' diode laser technique, or ...

Optimised switching of a SiC MOSFET in a VSI using the body diode and additional Schottky barrier diode

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
In this paper the switching behaviour of SiC MOSFETs is regarded with respect to the influence of the free-wheeling diode. A double pulse test was performed using two silicon carbide Schottky barrier diodes (SBD) of different rated currents and the intrinsic body diode of a silicon carbide MOSFET.
