Copper
strip winding is one of AGW's key areas of expertise. Advances in ferrite material
technology have led to higher frequency and higher current power supply transformers
and chokes. The struggle to place enough copper into the winding window and alleviate
the skin effect problem, means that winding with wide flat copper strip has become
more prevalent.
AGW has vast experience in this field and has
successfully overcome the problems associated with insulation, copper fill and
connections. A range of machines has been specifically developed by AGW to fulfil
the requirements of copper strip winding, giving maximum copper fill and allowing
each bobbin size to use its full power range.
AGW
Electronics Ltd., has over 25 years of experience manufacturing ferrite core transformers.
Working alongside customers and ferrite suppliers, the company collaborates in
the design of power conversion and high frequency products.
Recent
developments in ferrite material specifications have enabled designers to produce
more efficient transformers. AGW has developed copper foil winding techniques
to exploit the full capacity of these materials. AGW produces line, power, pulse
and drive transformers, used in many applications including switch mode power
supplies, inverter and motor drive controllers.
These transformers
can be manufactured in a variety of finishes and encapsulations, and from various
core types, including E, ETD, EF, RM, P and planar cores. Surface mount variants,
and other core types for specialised applications are also available - see FACILITIES.
AGW
Electronics Ltd. manufactures components used as common mode chokes, EMC suppression
chokes, PF chokes, switch mode power supply inductors, smoothing chokes, saturable
reactors and specialist inductors. Inductors and chokes can be manufactured in
toroidal or E-core style using material and sizes available from major core manufacturers
including: ferrite, iron powder, amorphous iron and silicon iron laminations.
AGW's
extensive facilities for toroidal winding, and specialised equipment allow winding
of heavy conductor material to cope with the high currents demanded by many modern
applications. This powerful combination of manufacturing capability and design,
testing and finishing, ensures a complete service to the customer.
Laminated
transformers can be manufactured to customer requirements from standard and specialised
parts. Mains power transformers are produced in the range 1 VA to 3k VA single
phase, and up to 25k VA 3 phase.
AGW also manufactures specialist
transformers using nickel based or other alloy laminations. Typical applications
include line matching, microphones, loudspeaker output, and military and aerospace
equipment. Depending on the application, PCB or chassis mounting options are available.
Planar transformers and planar inductors
have certain advantages over conventional winding systems. These advantages are
mainly in size and efficiency, with a typical efficiency of 98% being achieved,
while their low profile makes them especially suitable for high density equipment
designs. Other benefits of planar construction are very low leakage inductance,
and minimum Electro Magnetic Interference (EMI).
AGW
has developed enhanced ways to produce chokes and planar transformers. Using a
system of sealing the copper plates inside a plastic envelope, insulation integrity
is ensured. Another system using a winding technique similar to that used in conventional
chokes and transformers, provides a cost-effective alternative.
They
are available in power ranges from a few Watts to several Kilowatts, and their
terminations and mountings can be tailored to customer requirements.
AGW
Electronics Ltd. has the capacity to design and manufacture specialised windings,
and has been carrying out this type of work for more than 20 years, to suit the
special requirements of the telecommunications, leisure, entertainment, measurement,
defence and power industries. A further aspect of this work is our ability to
replicate obsolete items for use in the service sectors of these industries.
Typically
we can manufacture wave windings, self-supporting coils, high voltage windings,
antenna coils and IF transformers. Our experience in using specialised materials
enables us to meet our customers' requirements, with a variety of finishes and
encapsulations available - see FACILITIES.
AGW Electronics Ltd. manufactures
toroidal windings, both toroidal transformers and toroidal inductors . Toroidal
transformers can be manufactured in the range of 1 VA to 1k VA to suit customers'
input, output and dimension requirements. AGW can assist with the design and manufacture
of suppresssion chokes, common mode chokes, SMPS inductors etc., from ferrite,
iron powder or amorphous iron material, supplied by major core manufacturers.
AGW
has extensive manufacturing capabilities available to meet most requirements,
ranging from CNC toroidal winding machines to assisted pull winding, with finishing
operations which include mounting, potting and vacuum impregnation.
Manufacture & Design
of PCB & Light Electronic Assemblies
Using
modern methods and practices, supported by a suite of CAD software, AGW takes
designs from original specifications to finished product. We design circuits from
simple passive displays through to Microcontroller based logic, with our in-house
capability to generate code, and programme small to medium batches. Fast prototyping
of PCBs and mechanical parts is readily achieved through EDI, using industry standard
formats such as GERBER, DWG and DXF. We also have the resources to manufacture
production aids for use in manufacture and testing.
AGW assembles
using a variety of PCB styles - conventional, plated through, SMD and mixed technology.
Automated techniques such as flow (wave) soldering and infrared reflow are used
to maintain high standards. We also support light electrical and mechanical assembly,
giving us the capability of complete product manufacture.
To
many of our customers we provide the complete solution.
