Deshmukh, R.S. (author), Bauer, P. (author), Vahedi, H (author)This article presents a detailed procedure for deriving the generalized average model (GAM) of a dual active bridge converter. The proposed model incorporates higher orders of harmonic components to increase accuracy. Moreover, the turn ratio of the high-frequency transformer (N_t) is considered for realistic modeling, which removes the...journal article 2024

Li, Zhen (author), Chen, Zhiyuan (author), Law, Man-Kay (author), Du, S. (author), Cheng, Xu (author), Zeng, Xiaoyang (author), Han, Jun (author)With the advent of the lnternet-of-Things (1oT) era, sensor nodes are required in almost all fields to achieve a better interaction between humans and the environment. Piezoelectric energy harvester (PEH), which exhibits an equivalent electrical model of an AC current source /P in parallel with the inherent capacitor CP, is a promising...conference paper 2023

Tang, Z. (author), Pan, S. (author), Grubor, M. (author), Makinwa, K.A.A. (author)This article presents a sub-1 V bipolar junction transistor (BJT)-based temperature sensor that achieves both high accuracy and high energy efficiency. To avoid the extra headroom required by conventional current sources, the sensor’s diode-connected BJTs are biased by precharging sampling capacitors to the supply voltage and then discharging...journal article 2023

Gao, Z. (author), He, J. (author), Fritz, Martin (author), Shen, Y. (author), Zong, Z. (author), Spalink, Gerd (author), Alavi, S.M. (author), Staszewski, R.B. (author), Babaie, M. (author)This article introduces a low-jitter low-spur fractional-N phase-locked loop (PLL) adopting a new concept of a time-mode arithmetic unit (TAU) for phase error extraction. The TAU is a time-signal processor that calculates the weighted sum of input time offsets. It processes two inputs - the period of a digitally controlled oscillator (DCO)...journal article 2023

Ahmadi, M. (author), Shekhar, A. (author), Bauer, P. (author)Modular Multilevel Converters (MMCs) find increasing applications in medium to high-voltage systems. In such systems, reliability-oriented selection of power electronic switches becomes essential because higher modularity implies an increased number of components. The trade-off between the impact of higher modularity on converter reliability...journal article 2023

Xu, J. (author), Soeiro, Thiago B. (author), Wu, Y. (author), Gao, Fei (author), Wang, Y. (author), Tang, Houjun (author), Bauer, P. (author)A three-phase buck-type rectifier features a step-down ac-dc conversion function, which is considered as a prominent solution for electric vehicle chargers and telecommunication systems integrated to the grid above 380 V line to line. However, traditional solutions for those applications employ cascaded architectures with an ac-dc boost-type...journal article 2022
