In the operation of photovoltaic systems, one of the most important things to consider is tracking the maximum output power point. Maximum power point tracking is used in photovoltaic systems to increase the efficiency of these systems. A photovoltaic system is most efficient when the output power is at its maximum point. Today, there are various methods in tracking the maximum power point of photovoltaic systems. In this paper, the maximum output power point tracking in a photovoltaic system based on an z-source inverter is investigated and simulated using an enhanced conductivity algorithm and a two-loop control structure in an z-source inverter in which the loop The internal maximum current injects the active power into the network with a power factor of one, and the external loop controls the voltage of the capacitor network of the impedance source to stabilize the voltage. According to the simulation results in MATLAB/SIMULINK software environment, the effect of the proposed controller on improving the output response of the photovoltaic system is observed.
