High Efficiency Three Phase Transformer-Less MOSFET Inverter to Drive PMSM Motor
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 3
Abstract
A project proposed a new high efficiency three phase transformer-less photovoltaic (PV) inverter by using super-junction MOSFETs as main power switches. Here fifteen level topologies have been implemented by using H-Bridges. Fundamental switching scheme and Selective Harmonics Elimination were implemented to reduce the Total Harmonics Distortion (THD) value. The proposed inverter can also operate with high frequency by retaining high efficiency which enables reduced cooling system. To reduce the power demands scarcities, to minimize the electromagnetic interferences and to increase the energy efficiency by reducing the number of switches and size of output filter. Multilevel inverters are used to extract the power from solar cells. It also synthesizes the desired AC output waveforms from several dc sources. The simulation result shows the proposed system reduces the power demand scarcity and increase the efficiency using MATLAB/Simulink.
