This paper investigates a high-frequency and high-efficiency photovoltaic DC boost converter, which adopts the Boost full-bridge isolation circuit topology with active clamps. The conductance increment method is used as the maximum power point tracking algorithm. The small signal models of its power circuit and control circuit are established to obtain the system model and analyze its stability. The simulation results indicate that the ripple coefficient of output current is less than 3%, and the ripple coefficient of output voltage is less than 5%, which meets the stability requirements.<\/jats:p>","DOI":"10.3233\/jcm-194056","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T10:50:07Z","timestamp":1581418207000},"page":"817-826","source":"Crossref","is-referenced-by-count":0,"title":["Modeling and stability study of a high frequency and high efficiency photovoltaic DC boost converter"],"prefix":"10.66113","volume":"20","author":[{"given":"Shengshan","family":"Li","sequence":"first","affiliation":[{"name":"School of Communications, Qinghai Nationalities University, Xining, Qinghai 810000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Li","sequence":"additional","affiliation":[{"name":"School of Computer Science, Qinghai Nationalities University, Xining, Qinghai 810000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liangliang","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of the Ministry of Education on Smart Power Grids, Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","reference":[{"key":"10.3233\/JCM-194056_ref1","unstructured":"J.
