In order to solve the above problems, this paper studies the design of the LCL filter and ground short circuit problem of the hundred-kilowatt inverter. Firstly, an analytical method for calculating the DC bus capacitance and reactor of the inverter is proposed. The interaction between the DC bus capacitance and the reactor parameters and performance is considered in the implementation process. The parameters of the DC bus capacitor and reactor are given. Secondly, the one-to-ground short circuit of the inverter is studied, and the energy flow mode and mathematical expression of the double boost circuit, considering the influence of the leakage inductance of the power transformer, are given. Based on the above analysis, a method for determining the rectifier diode and IGBT, considering the one-to-ground short circuit of the inverter, is proposed. Finally, a one-hundred-kilowatt inverter is developed, and the corresponding experiments are carried out. The feasibility of the proposed scheme is verified by simulation and experiment.<\/jats:p>","DOI":"10.3390\/s23198211","type":"journal-article","created":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T04:39:30Z","timestamp":1696221570000},"page":"8211","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Study of the Protection and Energy Transmission Modes of One Phase Short Circuit to Ground in Inverters"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9906-8627","authenticated-orcid":false,"given":"Dezhi","family":"Chen","sequence":"first","affiliation":[{"name":"Key Laboratory of Special Motors and High Voltage Electrical Appliances, Ministry of Education, Shenyang University of Technology, Shenyang 110870, China"}]},{"given":"Zhixiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Special Motors and High Voltage Electrical Appliances, Ministry of Education, Shenyang University of Technology, Shenyang 110870, China"}]},{"given":"Shichong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Special Motors and High Voltage Electrical Appliances, Ministry of Education, Shenyang University of Technology, Shenyang 110870, China"}]},{"given":"Yun","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory of Special Motors and High Voltage Electrical Appliances, Ministry of Education, Shenyang University of Technology, Shenyang 110870, China"}]},{"given":"Wenbo","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Special Motors and High Voltage Electrical Appliances, Ministry of Education, Shenyang University of Technology, Shenyang 110870, China"}]},{"given":"Wenliang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, Shandong University, Jinan 250061, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Baburajan, S., Peyghami, S., Kumar, D., Blaabjerg, F., and Davari, P.
