The power electronics field has matured over the last sixty years. Today, static converters can efficiently transform electric energy to meet the requirements of many applications. And are the enabling technology for the integration of renewable generation into the electric grid. So power electronics will play a key role in the renovation of the existing electric network.
Many single phase transformerless inverter topologies with reduced leakage current have been introduced for grid tied photovoltaic (PV) applications in the past few years. These topologies are mainly classified on the basis of leakage current reduction methods: galvanic isolation with common mode voltage(CMV) clamping and without CMV clamping. The galvanic isolation can be achieved by incorporation of extra switches either on ac side or dc side of full bridge (H4) inverter topology for ac or dc decoupling respectively.
So you all are going to learn simulation of 10 different transformerless inverter topologies such as H5, HERIC , H6 and improved H6 topologies. All the topologies are designed for single stage conversion apart from that you will learn sinusoidal pulse width modulation strategies (SPWM)
