Short circuit without short circuit current

Marvin Tannhäuser has developed an electronic circuit breaker that provides an entirely new kind of electrical safety.

"Our semiconductor circuit breaker could represent a paradigm shift, much like the change from the electromechanical telephone to today's smartphone."

Electrical devices play an increasingly important role in our everyday lives. The semiconductor circuit breaker Marvin Tannhäuser and colleagues developed could make electrical energy even safer and more intelligent. Additional functions would no longer require other devices: The functionality of the switches can be expanded and customized through software, similar to smartphone apps.
