Modelling and analysis of modular multilevel converter for solar photovoltaic applications to improve power quality

The design of control circuit for a solar fed cascaded multilevel inverter to reduce the number of semiconductor switches is presented in this study. The design includes ‘binary’, ‘trinary’ and ‘modified multilevel connection’ (MMC)-based topologies suitable for varying input sources from solar photovoltaic's (PV). In binary mode, output voltage levels are obtained where Ns is the number of individual inverters. This is achieved by digital logic...
