This thesis proposes an implementation of a DSP-Based single-phase small-scale photovoltaic energy conversion system. The conversion system converts dc power generated by photovoltaic cells into ac power. A digital signal processor and a combined circuit with push-pull and full-bridge architectures are used in this study to reduce the complexity of the circuit design. Several operation and protection functions, such as maximum power point tracking, over/under voltage protection, over current protection, over/under frequency protection and detection of islanding operation are considered in the design. The operation performance of the conversion system at different stages is analyzed. The proposed conversion system can supply the local loads and feed excess power to the utility network with unit power factor (grid-connection mode), or it can supply loads exclusively (stand-alone mode). The simulation and experimentation results are presented and discussed to show the performance of the photovoltaic system and verify the feasibility of the proposed energy conversion system.
