Design and modelling of a photovoltaic system optimized by an analog control provided with a detection circuit of dysfunction and restarting of the system

In this article we analyze the design and the simulation of photovoltaic system (PV) optimized by an analog control (MPPT) provided with a detection dysfunction circuit and restarting of system. The unit guaranteed the tracking of the maximum power provided by generator statement and transfers it to the load. The results obtained show that the PV system thus conceived converges even in a random environment in a time lower than 100 ms towards the optimal conditions independently of the weather conditions and the load variation. The generator PV used in such system is module SP75 producing a power peak of 75 W.
