Maximum power point tracking technique

It is noted that to overcome the problem of mismatch between solar cells and a given load, maximum power-point tracking should be used. A simple efficient maximum power-point tracking technique is developed. The connection strategy depends on a very simple criterion which is the measurement of the solar radiation level. The control strategy is based on appropriate logic that compares the signs of dP/dt and dV/dt. The proposed technique is applied to the cases of resistive load, resistive load with battery, and dynamic load
