The distributed generation system has emerged to be an important research topic in the modern energy study, among which the expansion of generation capacity has a crucially high importance. Therefore, this thesis has configured a modularized inverter system structure, where the flexible capacity design was realized within this configuration in anticipation of improving the system operation reliability of distributed generations. In order to verify this proposed approach, both theoretical analysis and simulation tests have been performed. This is followed by the implementation of circuit hardware and measurement of acquired waveforms. Through these test results, they have supported the feasibility of the method for capacity expansion of distributed generation systems, thus further consolidating the reference value of the overall developed system.
