A high-frequency isolated dual-bridge LCL resonant dc/dc converter is presented for battery charging/discharging application in a small power wind generation application. With the help of LCL type resonant tank, zero-voltage switching is realized for all switches with output variation for all load range. A fundamental analysis approach is utilized to analyze the converter for the purpose of design. Based on the analysis results, a design example is given and verified with PSIM simulation.
