Abstract :
A discrete time-domain modeling and analysis technique applicable to all types of inner-feedback as well as noninner-feedback controlled parallel resonant converters (PRC) is presented. The nonlinear discrete time-domain equations representing the static and dynamic behavior of the PRC are derived and linearized about the equilibrium state of the PRC. The inner-feedback control law is linearized about the equilibrium state. the linearized PRC and the linearized inner-feedback control law are then combined to arrive at a linearized inner-feedback controlled PRC. This linearized modeling is used to analyze the small-signal characteristics of closed-loop and open-loop controlled PRCs
