Abstract

In conventional, a single-phase two-stage grid-connected micro-inverter for photovoltaic (PV) applications, DC/DC converter is used to obtain the highest DC power from the PV module. In this inverter, the rising voltage of the PV module to a grid voltage level is limited to a certain value. Moreover, the absence of isolation between the input and output makes the two-stage inverter less efficient. In this paper, a single-stage Push-Pull PV micro-inverter has been designed, simulated, and implemented to feed an alternating current (AC) to the load. A microcontroller PIC 16F877A is used to track the maximum power point of the panel and calculate the appropriate pulse width of the converter to keep the produced power as high as possible and used to generate sinusoidal pulse width modulation for this purpose. The PIC microcontroller is used to implement the incremental conductance algorithm maximum power point tracking (MPPT) technique Under various solar irradiation (G) and ambient temperature (T) conditions, the PV module is tested using Matlab/Simulink software. Experimental results obtained from a lab prototype are presented as well. The prototype will become a system feeding 1-phase AC-load from a single panel with a pure sinusoidal current waveform. The main advantage of this model is that it contains a real microcontroller, as can be found in reality, so that the same code for the MPPT algorithm used in the simulation will be used in real implementation
