A Four-Switch-Type Converter Fed Improved Photovoltaic Power System

The energy policy of India basically focused on renewable energy sources, and it comes after China, USA and Russia as far as energy production is concerned. In this paper, a four-switch-type converter is modeled, and the power loss model is described for improved photovoltaic (PV) power systems. The simulation responses are realized under different fault conditions. THD of grid voltage/current waveforms is found less than 5% which follow IEEE 519.
