Sydney, Australia: Asia Pacific Regional International Solar Energy Society Conference 2008 (ISES-AP 2008), 25-28 Nov 2008.http://hdl.handle.net/10092/3120This paper reports on the development of a cheap and simple grid connected inverters. It is intended for an integration of a small power photo-voltaic or wind turbine to a grid at low cost. The proposed inverter uses the single cycle control technique, which reduces switching complexity and forces the current waveform to match the voltage waveform. The control circuit operation for unity power factor output is explained. The method is simulated on PSCAD program for single phase system. The simulation output exhibits excellent performance with few components. The paper only considers the current wave-shaping control of the inverters and does not discuss other aspects of control such as maximum power point tracking. The simulations are compared with the prototype waveforms.enConference Contributions - OtherFields of Research::290000 Engineering and Technology::290900 Electrical and Electronic Engineering::290901 Electrical engineering
