Transformerless Photovoltaic Grid-Connected Inverters
This book focuses on a safety issue in terms of leakage current, builds a common-mode voltage analysis model for TLIs at switching frequency scale and develops a new modulation theory referred as
Scientific Reports 15, Article number: 8841 (2025) Cite this article Transformerless inverters with common ground structure are favoured in grid-connected photovoltaic (PV) systems primarily due to their ability to effectively suppress leakage current, eliminate transformer-related losses, enhance efficiency, and reduce costs.
Transformerless Grid-Connected Inverter (TLI) is a circuit interface between photovoltaic arrays and the utility, which features high conversion efficiency, low cost, low volume and weight.
The future of intelligent, robust, and adaptive control methods for PV grid-connected inverters is marked by increased autonomy, enhanced grid support, advanced fault tolerance, energy storage integration, and a focus on sustainability and user empowerment.
4. Grid-connected inverter control techniques Although the main function of the grid-connected inverter (GCI) in a PV system is to ensure an efficient DC-AC energy conversion, it must also allow other functions useful to limit the effects of the unpredictable and stochastic nature of the PV source.
