Small signal parameter of LLC converter

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
This paper presents the influence of circuit parameters on the small signal characteristics of the control to output transfer function of the LLC current resonant converter. The equivalent source model is employed for the analysis. To derive the dc gain and the internal resistance, circuit simulator is used.

Adaptive droop control strategy of parallel LLC converters

International Journal of Circuit Theory and Applications, 2023
AbstractWhen the resonant converters are connected in parallel, the output current is unbalanced without additional current‐sharing measures due to differences in resonant component. In the input‐parallel output‐parallel resonant converter system, the output voltage accuracy of the converter under the traditional droop control is analyzed when the load

A Study of LLC Converter with Buck Converter for CC-CV Charging

2020 8th International Conference on Power Electronics Systems and Applications (PESA), 2020
For having switching frequency equal to resonant tank frequency in LLC converter, a unity voltage gain can be achieved over the entire loading conditions but it is not suitable for the Constant Current-Constant Voltage (CC-CV) battery application. Also, the voltage gain characteristic of LLC converter is frequency dependent.

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.

IMPLEMENTATION OF 480W LLC RESONANT CONVERTER

2019
This study presents the design of an LLC resonant converter as using the leakage inductance of the transformer instead of the inductance in the resonance tank. With serial resonant characteristics, the power MOSFETs are conducted at zero voltage switching and secondary diodes are commutating under soft switching, so the switching power losses on the ...

A novel resonant LLC soft-switching buck converter

2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014
A new LLC resonant DC-DC buck converter is presented. The employed multi-resonant tank provides soft-switching conditions for all semiconductor devices independent from the operating voltages and the load current. The proposed converter enjoys useful advantages such as low element count, unconditional soft switching operation, self short-circuit ...
