The finalists, announced on Energy Efficiency Day, October 2nd, were selected from over 20 nominated companies. They were evaluated based on their potential impact on the power electronics industry, considering both production volume and social outcomes. The finalists are:

– Pulsiv (UK): High-efficiency 65W USB Type-C adapter design
– TCL (China): Single-stage multi-output power supply design for 32″ and 43″ TVs
– Solafam (Uganda): Hybrid solar-powered cold room for rural access

Trifon Liakopoulos, PSMA’s president, emphasized the organization’s commitment to energy efficiency across its various committees, forums, and activities. He expressed gratitude to all nominees, acknowledging the challenge in recognizing the numerous contributions to energy conservation.

The PSMA also notes the passing of Arnold Alderman (1939-2024), a respected energy efficiency advocate and long-time PSMA contributor.

The increasing adoption of soft switching power conversion topologies has highlighted the need for accurate quantification of energy stored in a power device’s output capacitance, as it impacts power converter efficiency. JEP200 addresses this need by providing standardized test circuits, measurement methods, and data extraction algorithms. The document is applicable to wide bandgap power semiconductors such as GaN and SiC, as well as silicon power transistors and diodes.

This new standard offers power electronics engineers a unified approach to testing new switching energy losses, particularly those related to output capacitance hysteresis caused by displacement currents. The guidance provided in JEP200 enables more precise system optimization, benefiting professionals working on high-frequency power conversion systems.

JEP200 demonstrates the JEDEC JC-70 committee’s ability to respond efficiently to industry requirements. By encompassing GaN, SiC, and Si power devices, this standard assists engineers in addressing design challenges arising from the proliferation of new power conversion topologies.

Power electronics companies worldwide are invited to join JEDEC and contribute to the ongoing work of the JC-70 committee. The next committee meeting is scheduled for November 6, 2024, in conjunction with the WiPDA conference in Dayton, Ohio. For more information or to get involved, contact Emily Desjardins (emilyd@jedec.org) or visit www.jedec.org.

Industry Session proposals may be submitted for an individual speaker presentation or for an overall session proposal. The total time allowed for each presentation is 25 minutes, including 5 minutes for Q and A. To submit a proposal for an Industry Session at APEC, presenters should prepare a 2-3-page proposal that provides a summary of the presentation content and a description of the target audience. Also, a short professional biography of the speaker should be included.  If proposing for a full session, a proposal for each of the individual presentations must be submitted. Presentations should have strong technical content and commercial references should be limited and only in support of the core content.
