A Novel Single-Stage Common-Ground Transformerless Buck–Boost Inverter [PDF]
In this article, a novel single-stage transformerless buck–boost inverter is introduced. The proposed inverter can share a common ground between the DC input side and the grid; this leads to having a zero-leakage current. The proposed inverter also provides the buck and boost voltage capabilities.

A Common Ground Five-Level Inverter Using Switched Capacitor
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019This paper proposes a common ground five-level inverter using switched capacitor. The main features of the proposed inverter are the common ground structure, multilevel output, and step-up input voltage. Because of the common ground structure, it can eliminate leakage current.
