Abstract

A relatively small and compact high voltage, high current power supply for a laser utilizes a plurality of modules containing series resonant half bridge inverters. A pair of reverse conducting thyristors are incorporated in each series resonant inverter module such that the series resonant inverter modules are sequentially activated in phases 360{degree}/n apart, where n=number of modules for n>2. Selective activation of the modules allows precise output control reducing ripple and improving efficiency. Each series resonant half bridge inverter module includes a transformer which has a cooling manifold for actively circulating a coolant such as water, to cool the transformer core as well as selected circuit elements. Conductors connecting and forming various circuit components comprise hollow, electrically conductive tubes such as copper. Coolant circulates through the tubes to remove heat. The conductive tubes act as electrically conductive lines for connecting various components of the power supply. Where it is desired to make electrical isolation breaks, tubes comprised of insulating material such as nylon are used to provide insulation and continue the fluid circuit. 11 figs.

The AGS main magnet power supply upgrade

Conference Sandberg, J; Casella, R; Geller, J; ...

The AGS Main Magnet Power Supply consists of a group of thyristor controlled power converters that operate from full rectify to full invert. In order to minimize ripple during the critical periods of injection and extraction 24 pulse converters are used for these portions of the cycle. The maximum voltage available in this mode is nominally 2,000 volts. The converters that are functional during this portion of the cycle are called the flat-top bank or ``F`` bank modules. During acceleration and invert where voltages of up to 12,000 volts are needed and where the ripple requirements are less stringent, groupsmore »« less
On the feasibility of a 1 MW inverter in less than a cubic meter volume for vehicle applications

Conference Podlesak, T; Singh, H

The Army Tank-Automotive Command (TACOM) which is committed to an All-Electric Tank, commissioned a study of the feasibility of 1 MW inverter in less than a cubic meter volume. TACOM has the constraint of very limited available volume, in that this volume is protected by armor and is thus at a premium. The study strategy was to evaluate a series of general inverter topologies, utilizing various power semiconductors. The first inverter evaluated was a standard, hard switched DC link with Gate Turnoff Thyristors (GTOs) as the power semiconductors. Since four quadrant operation is a requirement, two antiparallel GTOs are requiredmore »« less
The SURE House (Solar Decathlon 2015)

Technical Report Nastasi, John; May, Edwin

Coastal towns and cities across the Northeastern US, with their high population density, aged utility infrastructure, and unique geography, are increasingly vulnerable to climate change related storm events. In October 2012 superstorm Sandy highlighted the fragility of our current coastal building types and made clear the need for a new model of design and construction which works to understand and mitigate these weaknesses. Dramatic changes in public policy, championed by both The Federal Emergency Management Agency (FEMA) and the National Flood Insurance Program (NFIP) are driving the rebuilding of these shore communities, often resulting in costly renovations, un-sustainable neighborhood configurationsmore »« less

Positron Accumulator Ring (PAR) power supply

Technical Report Fathizadeh, M

The Positron Accumulator Ring (PAR) consists of 8 dipole magnets connected in series. These magnets are energized via one 12-pulse dc power supply. The power supply consists of four phase controlled half-wave wye group converters. Each of the two half-wave converters are connected through an interphase transformer to obtain a full-wave converter with 120{degrees} conduction. The input voltage for these two half-wave converters are 180{degrees} apart. The two full-wave converters are connected in parallel through a third interphase transformer. This type of connection of the converters not only provides the required output current, it also improves the input power factormore »« less
