Performance Analysis of Transistor Clamped H-Bridge Multi-reference Multi-level Inverter for Standalone PV System

In the current era, the presence of standalone power system has been prominent due to its advantages over the grid-interactive systems. The standalone power system is basically used for rural areas or remote locations that are not fitted within electricity distribution system. Here in this paper, a standalone photovoltaic (PV) system has been designed with two stages of conversion process such as boosting and inverting through boost converter and inverter, respectively. However, the first stage of conversion uses the basic boost converter lead by the second stage using a multi-reference switching scheme-based transistor clamped H-bridge multilevel inverter (TCHBMLI) using less switching devices compared to conventional. The multi-level inverter (MLI) and photovoltaic (PV) system combination are gaining popularity due to its usage for high power application, more sinusoidal output, low switching loss, and small filter size. Again, a detailed comparison has been depicted for a 5-level and 7-level multi-reference switching scheme-based multi-level inverter (MLI) for standalone photovoltaic (PV) system.
