Improvements 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 کاملDesign Considerations for an LLC Resonant Converter
Recently, the LLC resonant converter has drawn a lot of attention due to its advantages over the conventional series resonant converter and parallel resonant converter: narrow frequency variation over wide load and input variation and Zero Voltage Switching (ZVS) of the switches for entire load range. This paper presents an analysis and reviews practical design considerations for the LLC-type r...
متن کاملA Single-Stage LED Driver Based on Interleaved Buck-boost Circuit and LLC Resonant Converter
A single-stage LED driver based on interleaved buck-boost circuit and LLC resonant converter is proposed. The buck-boost circuit and LLC resonant converter are integrated by sharing switches, which can decrease the system cost and improve system efficiency. The input voltage of the buck-boost circuit is half of the rectified voltage, and two buckboost circuits are formed with the two half-bridg...
متن کاملChapter 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...
