scholarly journals MPPT Controller based Nine Level Inverter using Solar Power Generation System

This project proposed a solar power generation system is used for the MPPT (maximum power point tracker) controller in a nine-level inverter. The selection of the capacitor circuit is configured using nine-level inverter and a cascade-connected to the full-bridge power converter. The nine-level inverter contains seven powers. Electronic switches simplify the configuration of the circuit system. A single electronic power switch is switched to the high frequency at any time to generate a nine-level output voltage. The output of the photovoltaic solar panel system will be fed into an MPPT algorithm to obtain a maximum amount of energy from a photovoltaic system, and this technique is used for the generation of residential renewable energy. The output voltage of a photovoltaic solar system is completed by the use of the DC-DC power converter with independent voltage sources for an inverter and reduces the harmonics generated. The nine-level inverter reduced with switches in power generation.

There are two types of distributed solar power generation system stand-alone system and grid-connected system. In grid-connected system usually are equiped with additional transformer to transfer the energy from solar power to the grid. However, it has resulted in considerable cost in providing these systems. Therefore in this reserach develops boost transformerless inverter system. The proposed system consists of a boost converter and transformerless inverter. Boost converter is used to increse the dc voltage yield by photovoltaic (PV) and delivered to the grid by mean of  transformerless inverter.In order to maximize the power from PV, the proposed system is also designed with Maximum Power Point Tracking (MPPT) by changing the value of modulation index in the transformerless inverters. From the simulation results show that the system can work effectively in a variety conditions such as light intensity changed and fluctuating in the grid  voltage side.
