This converter is obtained based on conventional LLC resonant converter, replacing each switch to series-connected HB converter modules and splitting the resonance inductor to two inductors. It can change the DC voltage level with providing soft switching and easy fault-tolerant operation. Another MMR...

Design of a 1-MHz LLC resonant converter based on a DSP-driven SOI half-bridge power MOS module In this paper, the design of a 1-MHz LLC resonant converter prototype is presented. Aiming to provide an integrated solution of the resonant converter, a h... H De Groot,E Janssen,R Pagano...
A bidirectional LLC-C resonant converter with a normalized symmetry resonant tank is proposed for energy storage system. In the proposed LLC-C converter, two auxiliary switches are added to provide bypass path for each resonant capacitor. In either forward or backward operating mode, the converter ...
In the primary side are a full-bridge topology and an LLC resonant converter, while the secondary side uses a synchronous design with two VRMs (Voltage Regulation Modules) for the minor rails. The latter are on the modular PCB to reduce energy losses. ...
In this paper, a bridgeless single stage LLC resonant PFC converter is analyzed in time domain. This converter is simultaneously controlled by frequency and pulse width modulations techniques. Soft switching is greatly achieved thanks to the LLC resonant converter. Consequently, switching losses and EMI...
