ABSTRACT:
A protection circuit for a semiconductor device is disclosed. This circuit is connected in series with a power semiconductor device to be protected, and is comprised of a circuit breaker and current-limiting device. The current-limiting device limits the overcurrent, thereby providing a time allowance until the circuit breaker begins operate.
