Small signal model of PWM converters are derived from averaging method. In the case of resonant converters, the averaging method fails because tank currents and voltages have no dc component. Moreover, the phenomenon of "beat frequency dynamics" is not addressed in the averaging method. Although numerous modeling techniques are presented in literature to model resonant converter; they are either involved math or complex numerical computations. The state trajectories of resonant converters exhibit rotating behaviour and are analysed using Fundamental Harmonic Approximation (FHA).
