A Resonant Frequency Tracking Technique For LLC Converters Based DC Transformers
Authors: Yuqi Wei, Quanming Luo, Alan Mantooth
Extended Abstract:
Large circulating current and reactive power exist for the LLC / CLLC converter in the case that f s < f r , where f s is the switching frequency and f r is the resonant frequency; on the other hand, in the scenario of f s > f r …
