Arduino Uno Programming based New Five Level Inverter for Photovoltaic Applications

This article presents a novel five-level transformer-based inverter with inherent boosting abilities specially designed for photovoltaic applications. The key distinction of this proposed inverter lies in its three-leg configuration and a single transformer with an increasing output voltage of twice the input voltage, which results in a smaller size, more cost-effective and less complex inverter circuit. Additionally, this innovative design features fewer components, lower total voltage requirements, reduced voltage rate of change (dv/dt), and a decreased number of active devices compared to its counterparts. The article provides a comprehensive explanation of the circuit's operation and principles. It underscores the utilization of Arduino programming to generate the required control pulses for this five-level inverter. Finally, simulation results are included to validate the feasibility and performance of the proposed inverter, both in steady-state and dynamic operating conditions.
