Abstract

This paper presents a
new power electronic device, named power antifuse, providing an irreversible
bypassing function for the current after having been ignited by an external electrical
signal. The antifuse is a scalable power electronic device of 1 cm2
of active area. A pristine antifuse device provides an electric resistance of
more than 100 mega-ohms between the terminals. After having been
activated, the same antifuse device becomes a bidirectional bypass element offering
less than 20 micro-ohms of resistance to the electric current. The activation
time corresponding to the delay between the reception of the electrical trigger
signal and the full conduction of the antifuse is less than 10 ms even at
environment temperatures below -40°C. This paper shows how the integration of
antifuse devices in battery cells can be used to bypass and turn-off lithium-ion
battery cells thus improving the safety and availability of battery systems
used in transport applications like aircraft, railways, ship and road vehicles.
The characteristics of the proposed antifuse device make it also an ideal power
electronic device for bypassing faulty series connected sub-systems used in high-availability
applications or fail-operational redundant Systems.
