This chapter studies the LLC resonant converter operation in different modes. First harmonic approximation (FHA) is used to obtain the main converter characteristics in steady-state, including the dc voltage static gain. The obtained equations and curves are used to design circuit parameters and predict performance, which is verified through numerical ...
