A control strategy of Maximum Power Point Tracking base on dp/dv=0

According the output characteristics of photovoltaic cell, a strategy of Maximum Power Point Tracking (MPPT) based on dp/dv =0 is employed to obtain the maximum power output of PV array. By integrating the dp/dv signal of PV array, the target control values V*_s is acquired , and then a voltage feedback control system of PV array´s output voltage is presented based on DC/DC converter so that implements the maximum power point tracking of PV array´s power output. The theory analysis and simulations show that the proposed control scheme is effective and feasible.
