TL;DR
This paper introduces a new DC-DC converter and two-leg inverter for solar power systems to improve efficiency and reduce costs.
Contribution
A novel single switch inductor coupled DC-DC converter and modified MPPT controller for solar systems are proposed.
Findings
The modified MPPT controller improves solar power capture by reaching global maximum power points.

The two-leg inverter efficiently converts DC to three-phase AC power for grid integration.
Abstract
From the power generation history, the nonrenewable power sources utilization is falling extremely because of their demerits are high atmospheric pollution, more expensive, more catchment area for development, high fossil fuel transportation cost, less flexibility, and reliability. So, the sunlight systems are utilized in this work for feeding the power to the central grid. On the earth, the sunlight energy availability is more and it is more flexible for the installation. However, the sunlight photovoltaic (PV) module’s power production is very low. To improve the power generation of the PV network, a modified slider maximum power point tracking (MPPT) controller is proposed in the first objective and it is interfaced with the sunlight system for capturing more sunlight insolation thereby moving the functioning point of the solar system from local MPP place to required global MPP…
