An Accurate Design Algorithm for LLC Resonant Converters—Part I
This paper proposes a new approach to optimally design LLC converters. The core of the proposed approach is an accurate algorithm that can find all the possible designs satisfying the peak gain requirement. Designers can conveniently evaluate several design results and find the optimal one for their respective applications. Part I of this paper proposes the accurate design algorithm, which is developed based on time-domain resonant waveforms, law of charge conservation, and conservation of energy. Design procedures are also provided for computer automation.
