A single-stage boost inverter system for solar PV applications has a vast scope for exploration. The PV system can carry out technical developments in several areas such as PV cell production, power semiconductor switches, grid interconnection standards, and passive elements to improve performance, minimize cost and size of the PV system. To address these challenges, we present a cost-effective five-level SC-based grid-tied inverter for PV applications. The proposed inverter features seven power switches, a single SC, and one source, providing a two-fold voltage boost. Additionally, a current control structure is incorporated to regulate synchronized grid current injection. In this article, the proposed inverters are immune from current shoot-through problems associated with voltage source inverters, easing the requirement for PWM dead-times. They also provide a common-grounding feature between the grid-neutral and the negative-terminal of the PV panel, successfully suppressing the PV leakage current. The paper presented a novel topology for single-phase, single-stage boost inverters, including a shared ground. In contrast to the topologies currently in use, the proposed topology employs a single diode and capacitor, reducing one switch along with its associated gate driver circuit. The proposed MPPT can attain a constant output voltage at solar panel terminals. The average of this voltage can be taken as 517.8 V. The current delivered from the panel is 5380 A.Why do PV inverters need a boost circuit?Consequently, inverters need to have the ability to boost the output voltage of PV in order to maintain a stable AC voltage for the load. The traditional voltage source inverter is a step-down inverter. When the input voltage is low, the traditional voltage source inverter is usually added a DC-DC boost circuit at its front stage.
