Chapter 4 . High Frequency LLC Resonant Converter
With the development of power conversion technology, power density becomes the major challenge for front-end AC/DC converters. Although increasing switching frequency can dramatically reduce the passive component size, its effectiveness is limited by the converter efficiency and thermal management. In present industry implementations, due to the low efficiency PWM type topologies, DC/DC stage s...
متن کاملImprovements of LLC Resonant Converter
From previous discussion, the power stage could be designed according to the given specifications. The outcome of the design is the desired values for the components. For these components, power devices and capacitors are obtained from manufactures, which already reflect the state of the art technology. Within all these components, magnetic is the one need to be physically designed and built by...

متن کاملSmall Signal Analysis for LLC Resonant Converter
− In this paper, small signal characteristic of a LLC resonant converter is analyzed. LLC resonant converter was been reported in many papers recently because of its simple structure, high efficiency and high switching frequency capability. In order to make practical use of this topology, understanding its small signal characteristic is essential to design the control loop. For PWM converter, s...
متن کاملPerformance Analysis of Modified LLC Resonant Converter
In this paper a modified form of the most efficient resonant LLC series parallel converter configuration is proposed. The proposed system comprises of an additional LC circuit synchronized with the existing resonant tank of LLC configuration (LLC-LC configuration). With the development of power electronics devices, resonant converters have been proved to be more efficient than conventional conv...
