摘要: In this work is presented a study of the influence that basic components present in photovoltaic installations, have conventional Arc Fault (AF) protection systems, one DC/AC Converter and MPPT tracking system which both under command PWM switching control strategy. With deeper analysis type possible to develop an approach improve actual efficiency arc fault prevention systems. The possibility preventing faults by detecting voltage drop modifying converters disputed its work. This due fact has direct impact harmonic content current signals conventionally employed Detection Devices (AFDD), comparative simulation results between real ideal schematic validate statement above.
