Abstract
This study presents a 6-module cascaded H-bridgemultilevel converter design for AC split batteries in residential applications. It incorporates sorting-based balancing and level-shifted modulation for reduced harmonic distortion and current ripple. Two current controllers, PR and dq controllers, are employed for grid synchronization and quality control, with a focus on comparing their performance in terms of harmonic distortion, settling time, and steady-state error. Simulation results validate the effectiveness of sub-batteries balancing method during charging and discharging, and the stability of both controllers against the 5th and 7th harmonic distortion. Additionally, an experimental prototype with 6 battery emulators confirms the feasibility of the system and sorting algorithm.
