Abstract :
The MTOtm (MOS Turn Off )Thyristor, a replacement for the GTO (Gate Turn Off Thyristor), is a
MOSFET-GTO hybrid for power conversion in the 1 to 20 MVA range. The MTO thyristor is
significantly more efficient than the GTO by requiring a drastically smaller gate drive while
simultaneously reducing storage time, thus providing improved performance and reduction of system
costs. Other power bipolar-MOS devices are believed to have a ceiling of blocking voltage at about
3kV, but the design rules for voltage blocking applicable to the MTO thyristor are similar to those
used for other thyristors that presently achieve 9kV. In addition, the MTO thyristor easily lends
itself to conventional double-side-cooled packaging. This paper describes the concept of the MTO
thyristor, presents results of measurements made on experimental 4.5kV and 6kV devices and interprets
these with the help of numerical simulations, reports on the current status of development, and
discusses specifications of MTO thyristor models currently offered.
