Abstract: The switched-capacitor-based cascaded multilevel in- verters (CMI) have been emerging due to their voltage boosting ca- pability. Unfortunately, they suffer from impulse charging current and nonuniform operation. This article presents a topology termed as dual-T-type five-level CMI to resolve these problems without compromising the desirable voltage boosting characteristic. The main idea is to integrate a half bridge and an inductor to soft charge a capacitor that is connected in series with the dc source. The capacitor enables the voltage gain boosted to two, while the control of eight power switches that constitutes a dual-T structure enables five voltage levels generation. In addition, uniform opera- tion is achieved for cascaded extensions. The operating principle of the proposed topology is analyzed and elaborated. For validation, simulation, and experimental results of a prototype are presented.
Keywords: Cascaded multilevel inverter, dual-T-type topology, soft charging, switched-capacitor, voltage boosting
