| Abstract: | The grid tied photovoltaic system suffers a great loss because the performance of the transformer present in the inverter. The cost of the transformer is high and the maintenance cost is also high. Therefore transformerless inverter are widely used in grid tied photovoltaic system, due to the benefits of achieving high efficiency and low cost. The sinusoidal pulse width modulation of full bridge transformerless inverters can achieve high efficiency by using metal oxide semiconductor field effect transistor. Various topology has been implemented for transformerless inverter, but in that there is a problem of losses and reverse recovery characteristics. In our paper we are going to implement the center tapped H bridge transformerless inverter topology for grid tied photovoltaic system to avoid the losses and leakage current. A clamped branch is added in the transformerless inverter. The added clamping branch clamps the freewheeling voltage at the freewheeling period. As the common mode voltage is kept constant for the whole grid period that reduces the leakage current. The splitting structure of inductor at the region of grid side avoids reverse recovery voltage and this improves the efficiency of the system. The detailed analysis of our topology with the operational modes, leakage current analysis and design consideration were implemented and the proposed inverter is applied for single phase induction motor. |
