This chapter studies the LLC resonant converter operation in different modes. First harmonic approximation (FHA) is used to obtain the main converter characteristics in steady-state, including the dc voltage static gain. The obtained equations and curves are used to design circuit parameters and predict performance, which is verified through numerical ...

An improved design method of LLC resonant converter
2012 IEEE International Symposium on Industrial Electronics, 2012For LLC resonant converter, design of the resonant tank influences much of the performance. In traditional design ideas, the transformer magnetizing inductance values are more dependent on engineering experience. In this paper, a model is constructed based on the proposed “current angle” theory by accurately calculating the LLC resonant converter in ...

Voltage Feedback of an LLC Resonant Converter with a Rotary Transformer
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018Rotary assembly platforms are used in several automation applications, such as box-fill systems. In modern automatic machines, several actuators may be mounted on the rotating platform, but this architecture raises the problem of their feeding. The solution developed in this paper consists in adopting a LLC resonant converter that uses the leakage and ...
