Recent changes within the electricity industry, such as the 2% new renewable energy targets and "green" energy marketing schemes will see significant growth in the number of solar generating systems connected to the grid. The power electronics interfacing these systems to the grid can become smaller, less costly and more efficient. In this paper a 1.5kW, single phase, grid interactive inverter is proposed. This commercial inverter uses a high frequency link rather than the traditional 50Hz output transformer. Great care has been taken to achieve efficiency improvements that justify the additional complexity. This paper presents the results of a simulation study which was conducted to develop and verify the operation of the key control systems required by the inverter.
