Abstract
The Vehicle-to-Grid (V2G) technology utilizes electric vehicle batteries to store surplus electricity and supply it back to the grid when necessary. The V2G is an effective and economical solution, as well as a strong research direction for power electronics laboratories. In the onboard charger system of electric vehicles, the Power Factor Corrections (PFCs) are a Multi-Level Inverter (MLI) and are primarily modulated using the Sinusoidal Pulse Width Modulation (SPWM) method. However, Space Vector Pulse Width Modulation (also known as Space Vector Modulation (SVM)) is a superior technique. However, implementing SVM for MLIs is challenging as the total number of levels increases. This study introduces a modified SVM method for PFC to enhance the output voltage quality and compares this modified technique with the SPWM. The experimental outcomes demonstrate the benefits of the proposed technique.
