Abstract













In this work, the feasibility of the
Bipolar-Injection Field Effect-Transistor (BIFET) [5] in two different
Dual Thyristor type circuits [4] for an application as solid-state
circuit breaker (SSCB) is experimentally verified. The Dual Thyristor
type circuits are assembled from discrete silicon JFETs and a silicon
carbide BIFET and are electrically characterized at various
temperatures. The current-voltage characteristic shows the expected
regenerative self-triggered turn-off capability under over-currents and
the option to control the turn-off current by a passive resistor
network. The issue with the adverse positive temperature coefficient of
the trigger-current can be solved by putting the SiC BIFET in a cascode
arrangement with a silicon Dual Thyristor. In this configuration the SiC
BIFET provides the high voltage blocking capability and the silicon
Dual Thyristor with its negative temperature coefficient controls the
trigger-current. Transient analyses of both circuits indicate fast
switching times of less than 50 μs seconds. It is demonstrated for the
first time, that the SiC BIFET, due to its normally-on behaviour, used
in a Dual Thyristor type circuit is a promising concept for
self-triggered fuses in high current and high voltage applications.
