The rectifier has important influence on a DC/DC converter’s characteristics including the efficiency, the output voltage ripple and the dynamic behavior. By analyzing the difference between the center trapped rectifier and the double current rectifier, this document explains and demonstrates the advantage of the current doubler rectifier for DC/DC converters with especially high power but low ...

We have developed an electron beam ion source (EBIS) assembling three rings made of high-TC superconductor as a solenoid coil, which enables us to construct a “table-top” EBIS operated at the liquid N2 temperature with a strong magnetic field. Optimizing a pulse field magnetization procedure, the assembly yielded a magnetic field as high as 0.8 T under a persistent mode, which stably lasted mor...

The properties of a partially ionized plasma in a long cylindrical tube subject to a uniform axial electric field are investigated. The plasma is maintained by an external ionizing source balanced by bulk and surface recombinations. Collisions between neutrals, whose density greatly exceeds the density of charged particles, and of neutrals with ions are sufficiently effective for their velocity...

The properties of a partially ionized plasma in a long cylindrical tube subject to a uniform axial electric eld are investigated. The plasma is maintained by an external ionizing source balanced by bulk and surface recombinations. Collisions between neutrals, whose density greatly exceeds the density of charged particles, and of neutrals with ions are suuciently eeective for their velocity dist...

Guidelines for distributing a buck converter rectifier for application to three-dimensional (3-D) circuits is described. The 3-D rectifier exploits the properties of transmission lines to generate and distribute power supplies to different planes. As compared to a conventional rectifier, the proposed rectifier circuit only requires moderately size capacitors without the use of onchip inductors....

Single, double, and triple mutations progressively shift Shaker activation to more hyperpolarized potentials, resulting in an increase in the fraction of inactivated channels at negative resting voltages. The most negatively shifted mutation, the triple mutant, behaves like an inward rectifier. What is usually considered activation of an inward rectifier is, for the triple mutant, recovery from...

Power quality problems caused by significant increase of non-linear loads initiated intensive research in high power factor converters. Most of the modern power electronic systems like variable speed drives, DC power supplies and battery charging systems uses uncontrolled diode bridge rectifier. The uncontrolled rectifier system injects lot of harmonics in to the AC supply system there by reduc...

Considerable interest has recently focused on the weaver mutation, which causes inward rectifier channel alterations leading to profound impairment of neuronal differentiation and to severe motor dysfunction in mice (Hess, 1996). The principal targets of mutation are cerebellar granule cells, most of which fail to differentiate and degenerate in a premigratory position (Rakic and Sidman, 1973a,...

Three kinds of redox-mediated behavior were realized at an azobenzene-functionalized electrode, which has great potential for application in the field of molecular devices. According to these results, the functionalized electrode could act as either a cathodic molecular rectifier or anodic molecular rectifier.

6 LLE Review, Volume 73 A streak camera is an electro-optic instrument capable of resolving high-speed, low-repetition-rate, pulsed laser phenomena. The basis of the instrument is a streak tube. The image of the light to be analyzed is focused onto a photocathode at the input end of the streak tube. The photocathode emits electrons in response to the intensity of the light. The electrons, focus...
