Conversion of lines and substations to higher voltage has emerged in the industry as a viable alternative in meeting load growth or transmission requirements. This somewhat unconventional approach offers several advantages. Beyond the practical aspects such as use of available right-of-way and substation site, the economic advantages may be of ...

Threshold voltage based CMOS voltage reference
IEE Proceedings - Circuits, Devices and Systems, 2004The paper describes a CMOS voltage reference design that uses the temperature dependence of NMOS and PMOS threshold voltages to form a temperature-insensitive reference. No diodes or parasitic bipolar transistors are used. The circuit architecture accommodates a wide range of output voltages. A test chip is fabricated using a 0.5 /spl mu/m CMOS process.

Transactions of the American Institute of Electrical Engineers, 1926
Lack of voltage control is one of the objections which have been made to the use of rectifiers. The author describes a method of voltage control for rectifiers based on the use of a saturated core interphase transformer. Saturation of this device produces a gradual change from two three-phase rectifiers operating in parallel to one six-phase rectifier ...

Journal of Chromatography A, 1971
Abstract The different principles of high-voltage electrophoresis and the various types of high-voltage electrophoresis-apparatus now commercially available are discussed. High-voltage electrophoresis offers a rapid and reproducible method for the separation and identification of small amphoteric molecules.

Voltage gradients on high-voltage lines
Electrical Engineering, 1955AKNOWLEDGE of the voltage gradient which exists at the surface of a transmission-line conductor is necessary in many instances. This knowledge is especially important in studies regarding corona losses and radio interference.
