Analysis and modeling of integrated magnetics for LLC resonant converters

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
Shunt-inserted transformers are widely used to obtain high leakage inductance. This paper investigates this method in depth to make it applicable to integrate resonant inductor for the LLC resonant converters. The analysis and model of magnetizing inductance and leakage inductance for shunt-inserted planar transformers with and without air gaps are ...

Digital control of a half-bridge LLC resonant converter

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
Recently, LLC resonant converters are gaining more and more interest in DC/DC conversion due to their high efficiency and power density. Usually, they are used in low power applications, i.e. in the range of few hundred Watt and with constant output load, however they are very appealing in high power and renewable energy applications as well as in many

LLC parallel resonant converter design by scaling the LC converter

IEEE Transactions on Aerospace and Electronic Systems, 1998
An efficient and practical method for steady-state design of an LLC-type parallel resonant dc/dc converter (LLC-PRC) is presented. In general, the output characteristic curves of LLC-PRC can be obtained by multiplying the output curves of the LC-type parallel resonant converter (LC-PRC) by a ratio of the parallel and series inductances.

Study on LLC Resonant Converter for EMI Reduction

SSRN Electronic Journal, 2016
The problem of EMI reduction is the topic of major interest in recent years. EMI reduction is one of the aspects in the power converter operation and control. EMI Reduction refers to techniques such as spread spectrum clocking to reduce the effects of electromagnetic interference or EMI,EMI is defined as EMI = kIAf2 where I is the current, A is the ...

Resonance Parameter of Variable Mode LLC Converter for Auxiliary Converter

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
A precise modeling and resonant calculation method are proposed for variable mode LLC resonant converter. With normal operation of the converter, the redundancy of components is reduced. By establishing equivalent circuit model considering device characteristics, DC gain function is deduced.
