The National Ignition Facility, or NIF, currently under construction at the Lawrence Livermore National Laboratory will
contain the world’s most powerful laser. By the year 2003 the NIF laser will be a research tool allowing scientists a glimpse
into plasma interactions that are equivalent to those found in the center of the sun. Every eight hours the NIF will generate
1.8 MJ of 351-nm light carried by 192 pulsed laser beams and focus it onto a pea-sized target. This will result in a fusion
reaction between two isotopes of hydrogen, creating for a few hundred picoseconds stellar conditions. Synchronizing the
beams and diagnosing the fusion reaction requires generation and delivery of over 1000 precisely timed triggers to a multitude
of systems. The NIF Integrated Timing System (ITS) was developed to provide reliable, accurately timed triggers that allow
each client system to operate independently during periods of shot preparation and maintenance, yet be coordinated to a few
tens of picoseconds during the experiment. The ITS applies technologies developed for fiber communications and Two-Way
Time Transfer, and integrates them by way of a computer communications network to achieve distributed control, dynamically
configurable coordination and independence among timing channels, and integrated self-diagnostics.

Topological Issues in Single-Phase Power Factor Correction

The equipment connected to an electricity distribution network usually needs some kind of power conditioning, typically
rectification, which produces a nonsinusoidal line current due to the nonlinear input characteristic. With the steadily increasing
use of such equipment, line current harmonics have become a significant problem. Their adverse effects on the power system
are well recognized. They include increased magnitudes of neutral currents in three-phase systems, overheating in
transformers and induction motors, as well as the degradation of system voltage waveforms. Several international standards
now exist, which limit the harmonic content due to line currents of equipment connected to electricity distribution networks.
As a result, there is the need for a reduction in line current harmonics, or Power Factor Correction - PFC. In this dissertation,
we address several issues concerning the application to single-phase PFC of various high-frequency switching converter
topologies.
