A likely optimization of the transition and output inductors for activating the dynamic behavior of the phase-shifted zero-voltage-switching pulse-width modulated full-bridge (ZVS-PWM FB) converter is introduced. Five conversion models, including one energy-delivery state, two resonances, one energy-holding state, and one transition state etc., are explored and analyzed. Interestingly, the transition inductor is dominant only for the energy-transition period in the H-loop and the other four dynamics are mainly subject to the output inductor when the turns-ratio of the main transformer is greater than two. Design consideration for estimating the mentioned inductors is conducted and implemented by a 1-KW ZVS-PWM FB converter to assess the predicted dynamics.
