Yu, G. (author), Yadav, S. (author), Dong, J. (author), Bauer, P. (author)Triangular current mode (TCM) zero-voltage switching (ZVS) modulation method is widely adopted in power electronic converters to achieve acceptable efficiency in high switching frequency operations. For bidirectional dc-dc converters, in order to realize ZVS turn-on, a reverse inductor current can be utilized for this purpose through variable...journal article 2024

Yu, G. (author), Dong, J. (author), Soeiro, Thiago B. (author), Zhu, G. (author), Yao, Y. (author), Bauer, P. (author)This article introduces a three-mode variable-frequency zero-voltage switching (ZVS) modulation method for the four-switch buck+boost converter. This method makes this circuit concept well suited for applications, such as wireless power charging of electric vehicles, where this circuit operates as a power buffer between the resonant converter...journal article 2022

Zhu, G. (author), Dong, J. (author), Shi, W. (author), Soeiro, Thiago B. (author), Xu, J. (author), Bauer, P. (author)This article proposes a mode-switching-based phase shift control (MS-PSC) for wireless power transfer (WPT) systems, which is able to achieve power regulation, load matching, and wide ZVS operations simultaneously without using additional dc-dc converters. Based on the mode transitions between the full-bridge, mixed-bridge, and half-bridge...journal article 2022
