Circuit breaker device

摘要

A circuit breaker device (10) for interrupting a current flow in an electrical circuit and a method for interrupting current flow with such circuit breaker device (10) are proposed. The circuit breaker device (10) comprises a first switch arrangement (12) with a first silicon-based semiconductor switch (14) and a second silicon-based semiconductor switch (16), which are antisymmetrically interconnected with each other. The circuit breaker device (10) further comprises a second switch arrangement (18) with a first wide bandgap semiconductor switch (20) and a second wide bandgap semiconductor switch (22), which are series connected in a back-to-back arrangement. The first switch arrangement (12) is arranged in parallel to the second switch arrangement (18).
