Bus Voltage Deviation Automatic Compensation Control Based On Droop Control

2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2018
Droop control is an important control method in microgrids with distributed power supply. However, the traditional droop control does not consider the influence of line impedance between inverters, and will affect system stability and power sharing.

Reduction of threshold voltage deviation in Damascene metal gate MOSFETs

International Electron Devices Meeting 1999. Technical Digest (Cat. No.99CH36318), 2003
The Damascene metal gate transistors are found to exhibit characteristics superior to those of the conventional polysilicon gate transistors with respect to the threshold voltage deviation (/spl Delta/V/sub th/) and the subthreshold swing (S-factor) when the metal gate work function deviation (crystal orientation deviation) is suppressed by using the ...

Improvement of threshold voltage deviation in damascene metal gate transistors

IEEE Transactions on Electron Devices, 2001
The metal gate work function deviation (crystal orientation deviation) was found to cause the threshold voltage deviation (/spl Delta/V/sub th/) in the damascene metal gate transistors. When the TiN work function (crystal orientation) is controlled by using the inorganic CVD technique, /spl Delta/V/sub th/ of the surface channel damascene metal gate ...

Voltage deviation of POL converter with two-stage output filter

2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011
Obtaining a very low output filter has become a vital requirement for most of telecommunications applications. One from the common and practical ways to obtain a low output voltage ripple is to add a second stage LC filter. However, this creates a problem for the converter dynamics.
