A Novel Boost Cascaded Multilevel Inverter

This article presents a novel cascaded multilevel inverter as an alternative to the H-bridge (CHB). By adopting two H-bridges integrated with inductors and power switches, proposed topology is able generate five-level voltage merely single dc source. Voltage-boosting capability guaranteed despite its single-stage operation. A corresponding modulation technique also established charge boost constant duty-cycle while simultaneously generating ac voltage. Therefore, outperforms CHB in reducing isolated source count, enhancing gain, lowering magnitude. In addition, modularity preserved, where can be extended by cascading multiple modules. The operation feasibility of analyzed validated through simulation experimental results.
