Perry, Alexander G., Auteur ; Feng, Guang, Auteur ; Liu, Yan-Fei, Auteur |This paper proposes a novel design procedure of proportional and integral (Pl)-like fuzzy logic controller (FLC) for DC-DC converters that integrates linear control techniques with fuzzy logic. The design procedure allows the small signal model [...]

Zhang, Wanfeng, Auteur ; Feng, Guang, Auteur ; Liu, Yan-Fei ; Bin Wu, Auteur |For conventional digital power-factor correction (PFC) control methods, the duty cycle is calculated in every switching period. One main implementation barrier for the digital control of PFC is the limited switching frequency due to the limited [...]

Zhang, Zhiliang, Auteur ; Eberle, Wilson, Auteur ; Liu, Yan-Fei, Auteur |This paper presents a new nonisolated asymmetrical buck voltage regulator module. A transformer is used to extend the extremely low duty cycle of a conventional buck converter. Turn-off losses can be significantly reduced due to the extension of[...]

Han, Yongtao, Auteur ; Eberle, Wilson, Auteur ; Liu, Yan-Fei, Auteur |In this paper, a new and practical measurement method is proposed to characterize the planar transformer copper loss operating in a high-frequency switching mode power supply (SMPS). The scheme is easy to set up, and it provides an equivalent wi[...]
