Fault handling and fault clearance procedure
After the occurrence of a fault, the IGBT’s are stopped and the filter
determines the type of fault it is facing.
If it is not critical, the IGBT’s are restarted and the filter is back to normal
operation.
If the fault is critical, it is memorised and the filter conducts a fault clearance
procedure.
