Ch4. LLC Resonant Converter - Virginia Tech
vtechworks.lib.vt.eduLLC Resonant Converter 94 Chapter 4 LLC Resonant Converter 4.1 Introduction In previous chapters, the trends and technical challenges for front end DC/DC converter were discussed. High power density, high efficiency and high power are the major driving force for this application. Hold up time requirement poses big penalty to the system performance.
TEA19161 and TEA19162 controller ICs
www.nxp.comThe TEA1916 is a fully digital controller for high-efficiency resonant power supplies. It is a 2-chip combo, which includes the TEA19161 resonant/LLC controller and the TEA19162 PFC controller. Together with the TEA1995T dual SR controller, a complete resonant power supply can be built, which is easy to design and has a very low component count.

media.monolithicpower.cominductor-capacitor) is a resonant topology comprised of two inductors and one capacitor. It allows for zero-current switching of the main switches, thereby dramatically lowering switching losses and boosting efficiency. Figure 4 shows an example of an LLC resonant converter.
LLC Converter Design Note - Mouser Electronics
www.mouser.comload-level, LLC topology is proliferating throughout product categories and power levels. While this topology handles load variarations extremely well, it requires substantial upfront effort to configure a design to handle line variations – this must be fully considered in the resonant tank design, and a wider input range design will
Survey of Resonant Converter Topologies
www.ti.comanalysis method for resonant converters, fundamental harmonic analysis (FHA), is introduced along with a classical resonant converter structure. The popular LLC series resonant converter (LLC-SRC) [1] is then used as an example to show the linearization process in FHA. Voltage gains of 2- and 3-element resonant
