Abstract:

Photovoltaic (PV) renewable power generation is becoming increasingly common in industrial and household applications. However, these sources of renewable energy can cause environmental damage, increase power demand, and result in various losses due to interactions between converters and inverters. To address these issues, a proposed solution is to use a Photovoltaic (PV) input source tracking-based MPPT using CNN with switching operation and an output inverter connected to the grid. A battery is also included for backup to charge and discharge the input DC voltage. Voltage levels may be adjusted with this non-isolated DC/DC converter by using its buck and buck-boost modes. By balancing the input source, the non-isolated DC/DC converter connects the MOSFET switches based on the Selective Harmonic Elimination condition to reduce power loss and conduction loss by utilizing a switch device. The MOSFET switches operate at the fundamental frequency to achieve high voltage conversion in the VSI DC/AC inverter. The output results are analyzed through MATLAB simulation to determine the voltage drop and power loss across the switches.
