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.

LLC resonant converter with two resonant tanks
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010To cope with the high power density and low cost in switching power supply, LLC resonant converters with the two resonant tank circuits composed of resonance capacitors and two transformers are proposed in this paper. Each transformers used for the proposed resonant circuits are parallel connected in the primary and series connected in the secondary to

Resonant switch converters are a broad class of converters in which the PWM switch network of a conventional buck, boost, or other converter is replaced with a switch cell containing resonant elements. These resonant elements are positioned such that one or more of the switching loss mechanisms is eliminated. The resulting hybrid converter combines the

Resonant-tank control of parallel resonant converter
[Proceedings] Thirteenth International Telecommunications Energy Conference - INTELEC 91, 1993A control method, named resonant-tank control (RTC), is proposed for a parallel resonant power converter (PRC) operating above resonance. Using a simple linear combination of tank variables, it has potential for high-frequency DC-DC power converter applications.

Analysis of Resonant Converters
1984The load parameter, Q, and the ratio of the switching frequency to the resonant frequency, Fs/Fo, characterize the operation of resonant converters. An accurate do analysis of the series and parallel resonant converters is given in terms of these parameters whereby the conversion ratio, peak stresses, and diode conduction time are determined.

Resonant converters with secondary-side resonance [PDF]
, 2016 A family of quasi-resonant converters is disclosed as comprising a voltage source, a transformer having primary and secondary windings, and a switch for periodically coupling the voltage source to the primary winding, whereby a charging current appears on the secondary winding. The transformer exhibits a characteristic leakage inductance.

Topologies for three-element resonant converters
IEEE Transactions on Power Electronics, 1990Many of the limitations of two-element resonant topologies can be overcome by adding a third reactive element. However, using three elements greatly increases the number of possible topologies, making it very difficult to explore this class of circuits on a trial-and-error basis. An orderly search procedure that exposes a large number of new topologies,
