Electronics Transformers Technical Committee (ETTC)
Chair:
The current chair is listed as a member of the Administrative
Committee
Charter:
To advance the level of understanding of electronics transformers,
their component materials and other related magnetic devices and
apparatus.
Responsibilities:
- Sponsors tutorials, short courses, sessions at conferences and
workshops on issues related to electronics transformers and other
magnetic apparatus
- Publishes papers, special issues of the IEEE Transactions on
Power Electronics, bibliographies and PELS NEWSLETTER articles on
electronics transformers
- Sponsors standards for electronics transformers, their
component materials and other magnetic devices.
- Forms adhoc subcommittees to address particular technical
opportunities as they arise.
- Produces an annual report each January 1, tracing the work of
the committee during the previous year, work in progress, goals
for the new year and a current committee roster.
- Prepares an interim report in June describing progress against
goals and gives AdCom members an opportunity to discuss and
comment on the committee's activities.
Meetings:
The ETTC generally meets twice a year, once in the spring, usually
in conjunction with the Applied Power Electronics Conference (APEC)
and once in the fall, usually in conjunction with the Electrical
manufacturing & Coil Winding Association conference (EMCWA).
These meetings are used to review progress in the development of new
or revision of existing of IEEE standards maintained by the ETTC.
Topical subjects in the area of magnetic devices are also discussed
to determine if new standards, guides or recommended practices are
needed.
Membership:
The ETTC meetings are open to anyone with a genuine interest in
the design, manufacturing or the application of electronics
transformers or other related magnetic devices. Active membership
(voting membership) is governed by the guidelines of the ETTC
Operating Manual and of the PELS operation handbook.
Standards Development:
Existing Standards
The ETTC always welcomes input to its standards development. The
input for standard revisions can be presented at an ETTC meeting or
by contacting the appropriate working group chairman for an existing
standard. However only active ETTC members with an IEEE membership
may participate in the balloting of an IEEE standard.
A list of the IEEE standards and their respective scopes, that are
presently maintained by the ETTC, follows below. These standards may
be purchased by contacting the IEEE standards office at phone:
1-800-678-IEEE or via the IEEE
website .

Wide-Band (Greater Than 1 Decade) Transformers
- Standard 266-1969 - IEEE Test

New Standards Under Development
The ETTC always welcomes the opportunity to develop new standards
new or existing technologies as the need arises. The need for new
standards, recommended practices or guides can be presented at an
ETTC meeting or by contacting the chairman of the ETTC, Robert Beers

A list of some of the new standards, recommended practices and
guides is listed below:

Status: Gathering Information To Submit A PAR to the IEEE
Standards Board
Proposed Scope:
This recommended standard presents a number of different
materials, calculations and topologies for the electronics or power
designer to examine. Equations for standard calculation of losses and
operation are provided to enable the designer to evaluate the
application that they are examining. The information used in this
standard can be used for all types of inductors used in electronic or
power applications. Some information used in this standard can only
be used for specific applications as described herein. Several
references will be made to IEEE Standard 389 in reference to
temperature rise measurements.
The information provided in this standard is to be utilized as a
guide only. The information in this recommended standard include
those most commonly used in the inductor industry and many others
less commonly used.
