The applicability of package-embedded spiral inductors to switching buck converters is demonstrated. In the first step, the design and characterization process of package-embedded spiral inductors is investigated via comprehensive full wave electromagnetic simulations, while considering a realistic, multi-layer flip-chip package. An interleaved multi-phase buck converter with an array of package-embedded...
The article is based on wireless frequency-hopping communication technology, high-voltage bus switch contacts and temperature monitoring, combined with the main electric connection, the location of the measured points, name and temperature values are displayed on a computer screen at the monitoring center. ECS in the introduction of the loop current value, calculated temperature rise, given the ambient...
For the control target of capturing maximum power for variable speed wind turbine when the wind speed is below the rated wind speed, a switching “optimal” tracking controller of the generator angular velocity is designed. First, the generator optimal angular velocity is identified by using dynamic fuzzy neural network. Then a generator angular velocity optimal tracking controller is designed by using...
A novel fixed-Pulse Shape (PS) clock-jitter insensitive Return-to-Zero (RZ) feedback technique in CT ΣΔ modulators is presented. This technique offers a method to reduce the clock-jitter effect in feedback DAC. A switched-RC network and a zero-crossing detector are applied to generate jitter insensitive feedback pulse. This technique was verified in a designed 2nd order CT ΣΔ modulator. A stable 64dB...
Based on the principle of “magnetic resistance is minimum one”, adopting “analogism”, a switched reluctance planar motor (SRPM) design scheme has been proposed and developed. With the software of ADAMS (Automatic Dynamic Analysis of Mechanical System) and virtual prototype and simulation technique, the virtual prototype of three dimensions for SRPM is designed. By MATLAB software, the simulation model...
IPv6 deployment on campus network will play a tremendous role in IPv6 network construction. For realizing all campus IPv6 network deployment, this article introduces a kind of IPv6 department scheme and put in practice in Xuchang University. At present we have established the pure IPv6 network, realizing IPv4 network and IPv6 network interconnection and intercommunication through the NAT-PT and ALG...
