Power Semiconductors -
Bipolar
Dynex's Bipolar products
consist of Phase Control Thyristors (SCR), High Power Rectifier
Diodes, Gate Turn-off (GTO) Thyristors and associated diodes, and
Pulse Power Thyristors.
Our Phase
Control Thyristors feature the latest Ion Implant (i2) technology
which produces marked reductions in conduction losses which,
combined with reduced thermal resistance, gives substantially more
power handling capability. The voltage range extends from 1200V to
8500V and average current ratings from 500A to nearly 7000A.
Dynex
Rectifier Diodes are particularly suitable for IGBT inverter
front-end rectifiers, very high current applications like aluminium
smelting and trackside rectification. Voltages extend to 6kV and
current to 11kA.
Dynex is committed to
the continued production of GTO's to service both new build and
maintenance/refurbishment of existing railway locomotives. The range
of devices is suitable for applications in main line and light rail
traction drives and auxiliary converters.
Pulse
Power is an emerging technology and Dynex produces a range of
asymmetric 4500V devices in three different current ratings, which
gives a good trade off between voltage handling and extremely fast
turn-on. Devices can be supplied selected in sets for series
connection to achieve high voltage assemblies.
Power
Semiconductors - IGBT Modules
Dynex offers a
comprehensive range of high power IGBT and complementary diode
modules. The product family includes modules with voltage ratings
from 1,200V to 6,500V and current ratings from 100A to 3,600A.
Circuit configurations include single switch, dual switch, chopper,
half bridge and bi-directional options. All Dynex modules are
designed and constructed to meet the most rigorous performance and
reliability requirements in the marketplace. Our IGBT technology is
developed in-house by the Dynex R&D team, and manufactured in the
dedicated wafer fabrication and assembly facilities located in
Lincoln, ensuring complete control of the manufacturing process from
die through to fully tested modules. Applications for Dynex high
power modules include railway traction, marine drives, industrial
motor drives and wind power generation.
Power
Semiconductors - Power Assemblies
The
power assembly group design and manufacture a range of systems which
meet specific customer requirements for electrical, thermal and
mechanical performance. The long experience of providing systems
which utilise the Dynex semiconductor range and the unique
understanding of applications, enables the group to provide optimum
power assembly solutions, which can include protection and control
electronics. Air cooled and liquid cooled assemblies have been
designed for Thyristor, GTO, diode and IGBT applications.
SOS
Integrated Circuits
The Dynex facility in
the United Kingdom is unique in that it has the capability of
complete space component manufacturing on one site. The facility is
a world leader in the space components market with some 20 years
experience in the supply of products in to space programmes. SOS is
a mature technology with a long history of successful uses in space
programmes. Comprehensive Total Dose radiation data is available on
all Dynex Space products . The Quality system is comprehensive
conforming to all the requirements of MIL-STD 883 in the USA and
certified to ISO 9001. There is an increasing demand for space
systems that can survive radiation effects and ensure continued
operation. Of all the current silicon based semiconductor
technologies only SOS offers the necessary resistance to the hazards
of single event upset, transient and total dose radiation also
offering total immunity to latch-up effects. |
