This paper reports on the development of a cheap and simple grid connected inverters. Itis intended for an integration of a small power photo-voltaic or wind turbine to a grid atlow cost. The proposed inverter uses the single cycle control technique, which reducesswitching complexity and forces the current waveform to match the voltage waveform.The control circuit operation for unity power factor output is explained. The method issimulated on PSCAD program for single phase system. The simulation output exhibitsexcellent performance with few components. The paper only considers the currentwave-shaping control of the inverters and does not discuss other aspects of control suchas maximum power point tracking. The simulations are compared with the prototypewaveforms.
