Abstract

In general, symmetrical and asymmetrical capacitor-clamped boost converters and direct current capacitor voltage, unbalancing specially with lower output current Total Harmonic Distortion are frequent problems for inverters. In order to improve voltage quality, a boost converter with a flying capacitor and grid tie inverter is suggested in this study. It manages the direct current link voltage asymmetrically. Additionally, the boost converter with flying capacitor grid tie inverter system's output voltage dynamic responses are enhanced and simulated using MATLAB Simulink which in turn benchmarked using a scaled-down hardware module. Proportional Integral and Model Predictive Controller control strategies are suggested and implemented in the built hardware. The suggested system's voltage, current, and dynamic performance are examined. The results show that a 360 Watt output power can be delivered by the suggested combination of the described converter system. Additionally, grid-connected power converters and flying capacitor boost converters have lower current harmonics and better voltage regulation direct/alternating current converters, demonstrating the developed system's great suitability for power usage in home photovoltaic systems.
