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 ...

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
The paper discusses a new power converter circuit, the symmetrical resonant flyback power converter. Its fundamental mathematical analysis is presented, together with simulation results. The switches in the power converter operate with ZCS (zero current switching) at turn-on and with ZVS (zero voltage switching) at turn-off.

Analysis of a Resonant Converter Controlled by Triac
IEEE Transactions on Industry Applications, 1982Analytical and experimental considerations in the constant voltage transformer are presented. The constant voltage transformer consists of a linear reactor, a linear transformer, a capacitor, a triac and a feedback circuit. The feedback circuit is used to make the triac fire precisely at any angle from zero to ?/2 so as to keep output voltage constant.

Small signal simulation of resonant converters
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002The small signal behavior of a frequency controlled resonant converter is modeled as an equivalent PWM converter. By this model, a recently developed simulation algorithm for PWM converter is modified to simulate the open loop small signal behavior. PSPICE simulation results show that this approach is accurate and efficient.
