Patent number: 11940828Abstract: A voltage tracking circuit is provided. The voltage tracking circuit includes first and second P-type transistors and a control circuit. The drain of the first P-type transistor is coupled to a first voltage terminal. The gate and the drain of the second P-type transistor are respectively coupled to the first voltage terminal and a second voltage terminal. The control circuit is coupled to the first and second voltage terminals and generates a control voltage according to the first voltage and the second voltage. The sources of the first and second P-type transistors are coupled to an output terminal of the voltage tracking circuit, and the output voltage is generated at the output terminal. In response to the second voltage being higher than the first voltage, the control circuit generates the control signal to turn off the first P-type transistor.Type: GrantFiled: August 17, 2022Date of Patent: March 26, 2024Assignee: VANGUARD INTERNATIONAL SEMICONDUCTOR CORPORATIONInventors: Shao-Chang Huang, Yeh-Ning Jou, Ching-Ho Li, Kai-Chieh Hsu, Chun-Chih Chen, Chien-Wei Wang, Gong-Kai Lin, Li-Fan Chen

Publication number: 20220311288Abstract: A stator tooth includes an arc-shaped stator yoke portion and a stator tooth portion. The arc-shaped stator yoke portion extends along an arc having an axis as a center. The stator tooth portion includes a tooth body segment and two shoe-shaped structures. The tooth body segment, protruding along a centripetal axis from the arc-shaped stator yoke portion, has a first inner arc-shaped edge defined with a first center and a first radius. The centripetal axis passes through a center point of first inner arc-shaped edge, the first center and the axis. The two shoe-shaped structures extend oppositely, but symmetrically, from the tooth body segment, and each the shoe-shaped structure has a second inner arc-shaped edge and an inner-edge end point. The second inner arc-shaped edge, extending from the first inner arc-shaped edge to the inner-edge end point, has a second radius larger than the first radius.Type: ApplicationFiled: April 30, 2021Publication date: September 29, 2022Inventors: Lian-Shin HUNG, Ching-Chih HUANG, Yu-De LI
