A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

A simple constant-current electrocutaneous stimulator for high-impedance loads using low-cost, standard high-voltage components is presented. A voltage-regulator powers an oscillator built across the primary of a transformer whose secondary delivers, after rectification, the high-voltage supply to switched current-mirrors in the driving stage. Since the compliance highvoltage is proportional to...

Electra is a rep-rate Krypton Fluoride (KrF) laser that will be used to develop the technology required for an Inertial Fusion Energy (IFE) Power Plant. Electra will use the same type of architecture as the Nike 60 em amplifier [1], e.g. double-sided electron beam pumping of the laser gas, but it will run at 5 Hz and use technologies that can meet the IFE requirements for efficiency, durability...

*Work supported by Department of Energy contract DE-AC03-76SF00515 Abstract The optical design of the PEP-II electron and positron Injection Beamlines is described. Use of the existing high power, low emittance beams available from the SLC damping rings require that pulsed extraction of 9.0 GeV electrons and 3.1 GeV positrons for injection into the PEP-II rings occur in the early sectors of the...

New designs for Hybrid latch flip-flip (HLFF) and implicit-pulsed data-close-to-output (ip-DCO) flipflop circuits are proposed to improve the redundant switching activity, speed and power as these flip-flop circuits are basic building blocks of many timing elements. This paper evaluates and compares the performance of various flip-flop circuits which can reduce the effect of redundant switching...

-This paper proposes a low-power and area-efficient shift register using digital pulsed latches. The area and power consumption are reduced by replacing flip-flops with pulsed latches. This method solves the timing problem between pulsed latches through the use of multiple non-overlap delayed pulsed clock signals instead of the conventional single pulsed clock signal. The shift register uses a ...
