Abstract :
This paper reports on a new numerical model of GTO thyristor
embedded in a buck converter configuration. The GTO thyristor and
the free-wheeling diode undergo and/or generate various types of
stresses which cannot appear if the switches are modelled as
two-state resistors (R/sub ON/ and R/sub OFF/), as is the case
with many power circuit simulation softwares. Much more precise
models have been developed from semiconductor physics, but they
hardly apply to power circuit simulation because of the
associated large number of equations. The purpose of this paper
is to present a simple model of GTO thyristor derived from the
device physics and allowing it to represent the device
imperfections, in particular the behaviour at turn off. This has
been achieved with the use of bond-graph technique.
