TL;DR: In this paper, the authors proposed modulation schemes for making the LLC converter bidirectional, and showed that high efficiencies are predicted for both directions of power flow, though as the behavior of the resonant tank is substantially different in the reverse direction, some of the inherent benefits of the conventional LLC converter are lost.

Abstract: The isolated unidirectional LLC resonant converter is known for its outstanding efficiency and high power density. Little information has however been published about the possibility of transferring power in the reverse direction. This paper presents modulation schemes for making the LLC converter bidirectional. High efficiencies are predicted for both directions of power flow, though, as the behavior of the resonant tank is substantially different in the reverse direction, some of the inherent benefits of the conventional LLC converter are lost.

A comparison of half-bridge resonant converter topologies
Robert Louis Steigerwald
- 02 Mar 1987
TL;DR: In this paper, the half-bridge series resonant, parallel resonant and combination series-parallel resonant converters are compared for use in low output voltage power supply applications, and it is shown that the combination seriesparallel converter, which takes on the desirable characteristics of the pure series and the pure parallel converters, removes the main disadvantages of those two converters.

Snubberless Bidirectional DC–DC Converter With New CLLC Resonant Tank Featuring Minimized Switching Loss
Wei Chen,Ping Rong,Zhengyu Lu +2 more
TL;DR: Possessing the very optimal ZVS +ZCS soft-switching feature, this proposed converter will have a minimized switching loss if all of the main switches are implemented with metal-oxide-semiconductor field-effect transistors, and thereby, the proposed converter is fully soft switched and totally snubberless.
