Development of Micro-Inverter using Phase Modulated Converter

Increasing energy demand with rapid depletion of limited fossil fuel reserves has led to increase in global demand for clean energy sources and its harnessing technologies with higher efficiency and reliability. Solar energy has proved to be very promising in its usefulness as an effective, inexhaustible and environmental friendly source of energy. Building Integrated Photovoltaic (BIPV) technology amongs various methods of solar energy harvesting is a good solution to ensure better utilization of solar energy in rural and/or urban areas having many residential and commercial buildings. Each BIPV panel is connected to grid through an individual micro-inverter eliminating the problems of partial shading, dc arcs and space requirements etc. which is associated with conventional inverter technologies. The book deals with design and development of dual stage micro-inverter, where in dc-dc boost conversion is achieved using phase modulation topology. Selected topology and developed control schemes are validated in PSIM simulation environment. An experimental setup is developed with TMS320F28335 Digital Signal Controller (DSC) as embedded platform to validate the control strategies.
