| Abstract: | Fault current detection circuit is an important part of solid state circuit breaker, the detection speed can directly affect the action of solid state circuit breaker. This paper realizes the di/dt detection by introducing a detection circuit based on a second order band-pass filter circuit. The simulation and experimental results show that the circuit can detect the fault current in 3 ms under different fault conditions. |
