This innovative topology significantly reduces leakage current from the parasitic capacitor of photovoltaic (PV) panels, thereby minimizing the common\u2010mode voltage. Additionally, the inverter\u2019s fault\u2010tolerant design enhances reliability under conditions of power switch malfunctions. Mathematical analysis and circuit modeling in MATLAB\/Simulink validate the inverter\u2019s performance, revealing that it can achieve output voltage levels twice that of a conventional quadratic boost converter\u2010based inverter. To further verify its effectiveness, an 800\u2010W prototype was constructed, and a switching algorithm was implemented using an affordable Cortex\u2010M4 ARM microcontroller. Experiment results confirm the viability and performance advantage of the proposed topology.<\/jats:p>","DOI":"10.1002\/cta.4540","type":"journal-article","created":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T22:02:23Z","timestamp":1743458543000},"page":"6974-6989","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A New Transformerless Common Ground 5\u2010Level Inverter (TCG5LI) With Dynamic High\u2010Voltage Gain Boost and Fault\u2010Tolerant Capability"],"prefix":"10.1002","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0079-9601","authenticated-orcid":false,"given":"Dalya\u00a0Hamzah","family":"Al\u2010Mamoori","sequence":"first","affiliation":[{"name":"Department of Electrical Power Engineering Faculty of Electrical Engineering Universiti Teknologi Malaysia  Johor Bahru Malaysia"},{"name":"Department of Electrical Engineering Al\u2010MussaibTechnical College Al\u2010Furat Al\u2010Awsat Technical University  Najaf Iraq"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shahrin\u00a0Md.","family":"Ayob","sequence":"additional","affiliation":[{"name":"Department of Electrical Power Engineering Faculty of Electrical Engineering Universiti Teknologi Malaysia  Johor Bahru Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali\u00a0A.","family":"Abdullah\u00a0Albakry","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering Al\u2010MussaibTechnical College Al\u2010Furat Al\u2010Awsat Technical University  Najaf Iraq"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.\u00a0Saad\u00a0Bin","family":"Arif","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering Faculty of Engineering and Technology Aligarh Muslim University  India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Razman","family":"Ayop","sequence":"additional","affiliation":[{"name":"Department of Electrical Power Engineering Faculty of Electrical Engineering Universiti Teknologi Malaysia  Johor Bahru Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,3,30]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JESTPE.2019.2908672"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2021.3072170"},{"key":"e_1_2_10_4_1","doi-asserted-by":"crossref","unstructured":"R.
