The simultaneous high step-down or high step-up conversion with 97.6 % peak efficiency and injected current with THD < 2% is achieved. The leakage current problem, which is a main concern with the transformerless PV inverters, is around 20 mA. The indirect current control, especially at transition modes of operation is highly improved by utilizing a fast dead-beat control scheme. The working principles of the proposed converter show that the step-down and the step-up voltage gains are (D/(1-D)) 2 and D/(1-D) 2 , respectively. Furthermore, a 1 kW, 220 VAC and 200 VDC experimental prototype is implemented to confirm the theoretical achievements.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||IEEE||Journal:||IEEE Transactions on Industrial Electronics||Volume:||68||Issue:||6||Start page:||4838||End page:||4847||Copyright (published version):||2020 IEEE||Keywords:||Inverters; Inductors; Pulse width modulation; Topology; Capacitors; High-voltage techniques; Switches||DOI:||10.1109/tie.2020.2988240||Language:||en||Status of Item:||Peer reviewed||ISSN:||0278-0046||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
