To improve the power efficiency, following three approaches are taken: 1) optimum design of the transformer 2) use of the voltage doubler rectifier. 3) reduction of the winding loss of the transformer. The maximum power efficiency of 98.0% can be realized., 1st International Conference on Renewable Energy Research and Applications, ICRERA 2012; Nagasaki; Japan; 11 November 2012 ~ 14 November 2012, Renewable Energy Research and Applications (ICRERA), 2012 International Conference on, Article number 6477425; 2012}, pages = {1--4}, publisher = {IEEE}, title = {Power efficiency improvement of the composite resonant DC-DC converter}, year = {2012} }
