SCOPE Introduce existing Electronics Transformer Technical Committee

(ETTC) within IEEE PELS currently addressing standards and recommended practices for transformers and inductors − Identify group’s scope and limitations − Identify the IEEE documents maintained by the group − Identify the documents currently under revision along with the

issues that are being addressed Reach out to other magnetics industry related groups so as to

− Consolidate and/or organize view points for specific technical measurement issues such as ac power loss, radiated noise , etc.,

− Coordinate efforts to efficiently utilize limited resource pool of interested subject matter experts

Initiate discussions to determine if existing standards can be applied to specific emerging technologies or if new standards and/or recommended practices need to be developed

• Excitations: Sine-Wave current Vs Square-Wave Voltage – Applicability of tests

– Design verification in application versus industry specifications – Emerging triangular flux & arbitrary flux waveform methods Vs Square

wave voltage or Sine-Wave current excitation

• Operating Conditions Vs Recommended Test Conditions – Test conditions based on

– magnetic material properties – test equipment capability – end use application

• Precautions for magnetic components with gapped cores • distinction between core loss and other ac power losses

EMERGING TECHNOLOGIES (Solid State Transformers for Energy Routers - ICAID)

28

Energy routers are being developed with a new technology that combines rectification of ac to dc, dc-dc switch mode power conversion, dc to ac power conversion as well as communication and control protocols to replace existing distribution type transformers to accomplish more intelligent bi-directional power. The goal of this project will be to identify gaps in existing standards and recommended practices as the new technology is commercially introduced. Promote the new technology by identifying existing standards and recommended practices which forms an initial infra structure supporting the applicability and feasibility.
