A power electronic transformer (PET) with a cycloconverter on the grid side is being proposed in this paper for integrating several renewable energy sources to the grid. A single 1-phase multi-winding high frequency transformer connects multiple wind energy conversion systems and solar photovoltaic arrays to the cycloconverters using separate H-bridge PWM converters. The current is smooth and continuous due to the leakage inductance of the transformer; this results in the reduction of losses and also the use of thyristors ensures natural commutation of the leakage energy. The grid side currents and voltages have THDs within the limits as stipulated by the IEEE-519 standard. The principle of operation, control and modulation of the proposed PET topology is validated by simulations in MATLAB/ Simulink environment.
