Lyu, D. (author), Soeiro, Thiago Batista (author), Bauer, P. (author)This article presents an analysis, multiobjective design, and benchmark of three modified 3 phase shift full-bridge (PSFB) converters that are well-suited for electric vehicle (EV) battery charging applications, covering both typical battery voltage classes (400 and 800 V). These three modified PSFB converters, denoted as the t-PSFB, r-PSFB,...journal article 2024

Lyu, D. (author), Straathof, C.A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Bauer, P. (author)A variable switching frequency modulation for the Dual Active Bridge (DAB) converter is proposed in this paper. With this variable switching frequency modulation, the DAB converter can be operated in the ZVS-beneficial operational modes without the necessity to transition to others, thus a larger ZVS range for the DAB converter can be...conference paper 2023

Lyu, D. (author), Straathof, C.A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Bauer, P. (author)This paper proposes two modulation schemes for Dual Active Bridge (DAB) converters, with the aim of maximizing Zero Voltage Switching (ZVS) operation over a wide operational range. The first is a ZVS-optimized constant frequency modulation scheme, constructed based on the boundary conditions of ZVS operation. This scheme maximizes the number...journal article 2023

Grazian, F. (author), Soeiro, Thiago B. (author), van Duijsen, P.J. (author), Bauer, P. (author)In wireless charging systems, the H-bridge converter's switching frequency is set close to the system's natural resonance for achieving optimized zero voltage switching (ZVS). Variations to the system's natural resonance are commonly tracked by following the changes in the resonant current's polarity, i.e., current zero-crossings. The main...journal article 2021

Shekhar, A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)An important step in Voltage-Source Modular Multilevel Converter (MMC) design is the selection of adequate semiconductor blocking voltage class. This paper highlights that particularly for grid connected medium voltage applications, the choice of suitable switch blocking voltage class is not so straightforward. The market available switch...conference paper 2018
