A global
network
With ARCOL it’s about global ethics and local solutions.
This approach enables us to consistently offer the
personal service we have become renowned for.
Exceeding
expectations
Wind Turbines
The rapid growth in renewable energy systems,
particularly Wave, Solar and Wind-power, continues to
create demand for power components. One example
of ARCOL bespoke design is fitted as part of converter
electronics in a number of wind generator designs
connecting the ‘clean’ energy source to the grid.
Power Resistors for Wind Turbines;
Application example: The ARCOL HS resistors are
used in AC-DC-AC IGBT-based PWM converters for
voltage sharing and dc link discharge.
The resistor is selected to force voltage sharing across
the capacitor bank by setting the current through the
resistor to be several times the current through the
12 paralleled capacitors. The resistors also act as a
discharge circuit across the DC Link capacitor bank.
The ARCOL product range has characteristics tailored,
and ideally suited to these applications.
THEMIS Project
Have you ever wondered where that HS50, HS100 or
HS200 has gone? Well it has actually gone into space!
Some ARCOL resistors are being used in the NASA
‘Themis’ project in America. The units are used as heat
sources and have to operate in the vacuum of space.
THEMIS is a mission to investigate what causes
auroras in the Earth’s atmosphere to dramatically
change from slowly shimmering waves of light to
wildly shifting streaks of colour. Discovering what
causes auroras to change will provide scientists with
important details on how the planet’s magnetosphere
works and the important Sun-Earth connection. If you
are interested to know more – please go to
http://www.nasa.gov/mission_pages/themis/
main/index.html
Key attributes: High transient resistance and a wide
range of pulse capabilities matched to the application
with both high reliability and power density. They
are available with a variety of terminal types and
mountings to best suit customer requirements.
