This paper presents a novel concept of a DC-AC converter that ensures AC voltage modulation on four levels using a single branch and achieves voltage boosting. The proposed boost inverter is based on a single-stage topology and does not use a DC-DC b

Abstract In recent years, common ground (CG)‐type transformerless (TL) inverters have been paid more attention. However, the existing topologies have more voltage stress on either switch or on capacitor voltage or in both. This article proposes a n
