| Abstract: | LLC half-bridge resonant converter has been widely studied due to advantages of high efficiency and high power density.The accurate parameters can create a precondition for LLC resonant converter to achieve high efficiency and satis-factory soft switching.A parameter design strategy based on frequency domain is described,a more accurate design strategy is introduced based on frequency and time domains in order to optimize the parameter.A LLC resonant converter prototype which employ the latter strategy is d... |
