Abstract

The single bus cascaded H-bridge inverter (CHB) with DC-DC converter for improves the voltage gain using photovoltaic system. The multi input in H bridge inverter for decreasing the harmonics using single dc bus. The photovoltaic based boost converter for enhance the voltage gain and it is fed into various converter circuit which are connected in parallel. The proposed inverter has decreased the utilization of power switches and increases the efficiency. These single bus cascaded H bridge multilevel inverters used to reduce the Total harmonic distortion in switches when the levels increased and power quality of the photovoltaic system is also improved. The photovoltaic based single dc source connected with cascaded H-bridge inverter is implemented using the Matlab/Simulink tools.
