MULTI-MODULAR CONNECTOR TO PREVENT PV TO GRID MISMATCHES

The modular cascaded H-bridge multilevel inverter, which requires a remote electricity source for every H-bridge, is an electricity/ac cascaded inverter topology. The separate electricity links within the multilevel inverter make independent current control possible. This paper presents a modular cascaded H-bridge multilevel solar (PV) inverter for single- or three-phase grid-connected programs. The modular cascaded multilevel topology helps you to enhance the efficiency and versatility of PV systems. To understand better usage of PV modules and increase the solar power extraction, a distributed maximum power point monitoring control plan is used to both single- and three-phase multilevel inverters, which enables independent charge of each electricity-link current. For 3-phase grid-connected programs, PV mismatches may introduce unbalanced provided power, resulting in unbalanced grid current. To resolve this problem, a control plan with modulation compensation can also be suggested. Simulation and experimental answers are given to verify the practicality from the suggested approach. An experimental three-phase seven-level cascaded H-bridge inverter continues to be built utilizing nine H-bridge modules. Each H-bridge module is linked to a 185-W solar power.
