IEA 4E TCP-PECTA: Power Electronic Conversion Technology (Working period 2021 - 2024)

The Power Electronic Conversion Technology Annex (PECTA) is one of 4 Annexes of the IEA 4E TCP. PECTA shall assess the efficiency benefit of the emerging WBG technology for different relevant power electronic applications and furthermore serves as an independent knowledge platform for policy makers and all kind of parties and stakeholders that are interested in WBG.

Short Description

The Power Electronic Conversion Technology Annex (PECTA) is one of four Annexes (EDNA, EMSA, SSL and PECTA) within the IEA 4E TCP (Technology Collaboration Program of Energy Efficient End-Use Equipment) and was launched in march 2019.

Overall Goal of PECTA

The overall goal of PECTA includes collecting and analyzing information on new wide band gap (WBG) based power electronic devices, coordinating internationally acceptable approaches that promote WBG-based power electronics and developing greater understanding and action amongst governments and policy makers.

Specific Goals

  • Collecting and analyzing information on new WBG-based power electronics as energy efficient technology.
  • Share expertise and pool resources on this energy efficient technology
  • Coordinating internationally acceptable government approaches that promote WBG-based power electronics.
  • Developing greater understanding and promote government actions that encourage the use of WBG-based power electronics.
  • Accompanying and supporting international standardization public organizations (e.g. IEC).

The annex is split into 2 different stages:

  • Introduction phase (March 2019 – April 2020) and
  • Established phase (May 2020 – February 2024)

During the Introduction Phase two main tasks have been investigated in detail:

  • Task 1: Validation of efficiency potential of different WBG applications
  • Task 2: Identification of development of a short and long-term roadmap for power devices in order to determine a global view.

For the currently ongoing "Established Phase", the following specific tasks were defined based on the key findings derived from the "Introduction Phase" and are now being processed:

  • Task A: Completion and Updating available efficiency figures
  • Task B: Energy and environmental related life Cycle Assessment (LCA)
  • Task C: Revision of elaborated Application Readiness Map
  • Task D: Policy measures and mapping with applications on a timeline
  • Task E: Measurement of Power Supply Efficiency
  • Task F: Standards to support the WBG-Market entrance

Main result of the Austrian participation is the generation of knowledge in order to assess applicability of possible long-term concepts considering integration of WBG, and coordination of the Annex as Operating Agent and leading an Academic Advisory Group. Furthermore, the PECTA serves as independent knowledge platform, which allows Austrian policymakers and industry to support the market entrance of WBG technology.
