Abstract

An inverters are convert DC voltage into AC voltage, are crucial components of contemporary electrical systems because they enable the use of electricity for a variety of domestic and commercial applications. Research on AC grid connected universal bridge for PV generation is being established for PV system at the maximum power point tracking (MPPT) in order to increase the energy of solar generation and the quality of the power. This work presents the layout and performance of energy electronic converter that can independently set up both active and reactive for PV array power implementation with a single-phase electrical grid. This research is essentially intended to convert DC source voltage to AC voltage from a battery utilizing an inverter circuit design, and a 50Hz, 230W, 3KWh solar PV system is designed for optimal performance. Various sub-circuits are coupled for overall functioning. Additionally, the power factor & quality are increased. Furthermore, a simulation model based on MATLAB/SIMULINK is developed in accordance with the fundamental concepts of AC inverter control system and inverter analysis.

Introduction

The text discusses renewable energy generation with a focus on photovoltaic (PV) systems, which convert sunlight into electricity efficiently and cost-effectively. PV systems often connect to AC grids via converters like DC-DC Boost converters and Voltage Source Inverters (VSI) to maximize power output despite the non-linear nature of solar energy. DC systems are increasingly preferred due to their simpler integration with storage and fewer issues like harmonics or synchronization.

Maximum Power Point Tracking (MPPT) algorithms, such as Perturb & Observe (P&O) and Incremental Conductance (INC), adjust the duty cycle of DC-DC converters to optimize energy extraction from solar panels under varying conditions like temperature and irradiance.

AC inverters convert DC from the PV system to usable AC for the grid, though some inverter types require an existing AC source to operate. The study highlights the design and simulation of a PV system using MOSFET-based Boost converters and universal bridge inverters modeled in Simulink.

The PV modeling system is based on an equivalent circuit with resistors accounting for losses, and factors such as solar temperature and radiation affect power output. Efficient PV systems maintain operation at the maximum power point through suitable load compatibility and converter control, ensuring optimal power generation and grid integration.

Conclusion

It is concluded from this paper that by getting maximum load on solar PV on AC grid system, its efficiency and power can be improved. In the coming time, this can be done in a better way so that good prosperity can be achieved by reducing the battery capacity. By increasing the maximum power in the solar array using a Boost converter, it can be injected into the AC grid to generate energy for some good purposes in industries. This research paper helps in tracking the power at the maximum point with better incremental accuracy through its MPPT P&O method. Also this can be achieved by connecting the PV system with Boost converter to the grid with good AC load. The simulation model gives 350 V output voltage and output power at the maximum power point with DC voltage to stabilize the system, it accurately obtains the sinusoidal waveform.
