Parallel resonant converter with LLC-type commutation
IEEE Transactions on Aerospace and Electronic Systems, 1989It is shown that by using a proper transformation of state variables, the third-order system of the parallel resonant converter (PRC) with LLC-type commutation can be analyzed by means of a two-dimensional state-plane diagram. A set of characteristic curves which can be used for the converter design is derived from the analysis.

PWAM control of bidirectional LLC resonant converter
2013 1st International Future Energy Electronics Conference (IFEEC), 2013This paper proposes an improved bidirectional LLC resonant converter with pulse width and amplitude modulation (PWAM) control method. With the proposed PWAM control method, the converter can be operated with a much wider voltage range at a fixed switching frequency, which can be equal to the resonant frequency.

Optimal Design Methodlogy for LLC Resonant Converter
Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006. APEC '06., 2006Although LLC resonant converter can achieve wide operation range with high efficiency, lack of design methodology makes it difficult to be implemented. In this paper, based on the theoretical analysis on the operation principles during normal condition and holdup time, the relationship between converter efficiency and operation range with different ...

LLC resonant converter with quality factor limiter
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016This paper presents the concept of a high-power DC/DC class of converters with a Q-factor limiter based on a serial LLC type resonant circuit. The Q-factor limiter allows highly accurate determination of the voltage/current limit values in the resonant circuit's passive elements thus significantly increasing immunity to transient states.

Small-Signal Modeling of LLC Resonant Converters
2020 IEEE International Conference on Information Technology,Big Data and Artificial Intelligence (ICIBA), 2020Owing to the advantages of high efficiency and high power density, LLC resonant converters have been widely used. Generally, in order to design the closed-loop regulator, the small-signal model is necessary. Nevertheless, the small-signal model of LLC resonant converter is usually complex and inconvenient to be used to design regulators. In this paper,

IMPLEMENTATION OF 480W LLC RESONANT CONVERTER
2019This 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 ...
