A Novel Series of Intelligent Power Modules “V1 - MITSUBISHI ELECTRIC CORPORATION





V1-series is a new intelligent power module (IPM) which is mainly developed to increase
the efficiency of motor drives, power supplies like DC/DC converter. For this purpose
several new technologies have been implemented such as a new full gate CSTBT™ chip
and a newly developed dedicated control IC. The V1-series is a power module focussing
on applications in the two digit kW- class and, hence it has a line-up of 200A/300A/450A
in the 1200V class, and 400A/600A rating in 600V. Chip technology and structural
improvements reduce the effective junction temperature and increase the power and
thermal cycling capability of this family of IPMs while keeping widely terminal
compatibility with previous 2 in 1 V-series IPMs.

Compact Fluorescent Plug-In Ballast-in-a-Socket

Final Report
Compact Fluorescent Plug-In Ballast-in-a-Socket
DOE Cooperative Agreement No. DE-FC26-99FT40630
NETL Project Manager: Ed Christy

Period Covered: December 22, 1999 - December 21, 2001

THE FULL PAPER IS HERE:

Executive Summary
The primary goal of this program was to develop a ballast system for plug-in CFLs (compact fluorescent
lamps) that will directly replace standard metal shell, medium base incandescent lampholders (such as
Levition # 6098) for use with portable lamp fixtures, such as floor, table and desk lamps. A secondary
goal was to identify a plug-in CFL that is optimized for use with this ballast. This Plug-in CFL Ballastin-
a- Socket system will allow fixture manufacturers to easily manufacture CFL-based high-efficacy
portable fixtures that provide residential and commercial consumers with attractive, cost-effective, and
energy-efficient fixtures for use wherever portable incandescent fixtures are used today. The advantages
of this proposed system over existing CFL solutions are that the fixtures can only be used with highefficacy
CFLs, and they will be more attractive and will have lower life-cycle costs than screw-in or
adapter-based CFL retrofit solutions. These features should greatly increase the penetration of CFL’s into the North American market.

Ray Kurzweil - Scientist, inventor, entrepreneur, author and futurist

ComputerHistory — 20 de setembro de 2009 — [Recorded July 13 2009] Ray Kurzweil is a 21st century polymath. He is a scientist, inventor, entrepreneur, author, visionary and futurist. As a scientist and inventor he has pioneered work in optical character recognition (OCR), speech recognition technology, and electronic keyboard instruments. As an entrepreneur, Kurzweil has founded businesses in the fields of OCR, music synthesis, speech recognition, reading technology, virtual reality and financial investment. He is the author of numerous books on health, artificial intelligence (AI), the technological singularity and futurism. The Kurzweilian version of the future is the inevitable merger of humans and intelligent machines.

Verification of Rogowski Current Transducer’s



















Verification of Rogowski Current Transducer’s
Ability to Measure Fast Switching Transients
C. R. Hewson, W. F. Ray and R. M. Davis
Power Electronic Measurements Ltd.,
164 Lower Regent Street, Beeston, Nottingham, NG9 2DJ, UK

Abstract - Rogowski current transducers combine a high
bandwidth, an easy to use thin flexible coil, and low insertion
impedance making them an ideal device for measuring pulsed
currents in power electronic applications. Practical verification of
a Rogowski transducer’s ability to measure current transients due
to the fastest MOSFET and IGBT switching requires a calibrated
test facility capable of generating a pulse with a rise time of the
order of a few 10’s ns. A flexible 8-module system has been built
which gives a 2000A peak current with a rise time of 40ns. The
modular approach enables verification for a range of transducer.
