Yang, Zhe (author), Liu, Zhou (author), Zhang, Qi (author), Chen, Zhe (author), de Jesus Chavez, Jose (author), Popov, M. (author)The traditional fault control strategy of converter-interfaced renewable energy sources (CIRESs) may bring about a lower sensitivity level or misoperation of fault component-based directional elements. To overcome this problem, a new control scheme is proposed to adjust sequence impedance angles of CIRESs by computing suitable current...journal article 2023

Lu, Qi (author), Li, Shuangmu (author), Zhao, Bo (author), Jiang, Junmin (author), Chen, Zhiyuan (author), Du, S. (author)Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...journal article 2023

(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This paper presents an area- and power-efficient application-specified integrated circuit (ASIC) for 3-D forward-looking intravascular ultrasound imaging. The ASIC is intended to be mounted at the tip of a catheter, and has a circular active area with a diameter of 1.5 mm on the top of which a 2-D array of piezoelectric transducer elements is...journal article 2018
