摘要：LLC resonant converter was wildly used for its high switch frequency and high power density. Its main topology is a second order resonant system whose feature varies with load. Thus, it is equivalent to a nonlinear system. However, it is difficult to satisfy the demand of chargers by using only fixed controlling parameters. The paper uses the fundamental analysis method to build system model, and through adjusts controlling parameters to suit the time varying feature. The experiment result shows the validity of proposed controlling method.
