This thesis presents the design and implementation of a DSP-Based single-phase single-stage photovoltaic (PV) energy inverter system which can extract maximum power from solar array. The main control scheme of the photovoltaic inverter system is: a perturbation and observation (P&O) method commonly employed for industrial applications as the maximum power point tracking algorithm cooperate with a digital sinusoidal pulse width modulation with unipolar voltage switching scheme to control the output frequency.
For a market development issue, single-stage topology provides the benefits of low cost, easy implementation and improved overall system efficiency compared with conventional two-stage structure. Besides, this thesis proposes a new current sampling technique to enhance the system flexibility and the MPPT accuracy of maximum power point tracker (MPPT). Finally, the control of the photovoltaic inverter system established by a digital signal processor Texas Instruments TMS320F2808 is applied together with the software algorithm for the experiments to certify the proposed scheme.
