Due to the fast development in electrical devices,which depend on converting AC power system from the grid to DC,those devices become more sensitive to power quality problems and they affected easily by small disturbances in the system.In addition,people definition of power quality has changed through last decades.They do not just want electrical supply to be reliable,they also need their power supply to be highly compatible with their devices and do not cause any shut down to the load.The most ...
