VisIC Technologies announces its participation in APEC 2023 and presents a plenary session and an industry session. Conference attendees are welcomed in a designed booth in which ViSiC's latest Innovations and breakthrough technologies are presented. The Applied Power Electronics Conference (APEC) focuses on the practical and applied aspects of the power electronics business. APEC includes many areas of interest for anyone involved in power electronics. VisIC Technologies will be present at Booth# 547 at APEC 2023.
Plenary Session
Speaker: Dr. Tamara Baksht, CEO & Co-Founder
Title: GaN HEMT for Electric Car Inverter: Breakthroughs and Challenges
Time: Monday, March 20, 2023, 3:30 p.m. – 4:00 p.m. ET
Abstract:
The mobility industry is living through the most dramatic changes since the invention of the internal combustion engine and the standardization of the manufacturing process. Society and governments are looking for zero-emission transport, while car makers are seeking the most efficient way to manufacture low-cost and long-distance electric cars. In this context, inverter efficiency became the critical performance parameter, and semiconductors with low loss switching energy, such as SiC and GaN are getting into the spotlight. In this keynote, the successful development of a three-phase GaN-based inverter reference design with 400 V bus voltage and 400 A RMS current is discussed and the results are presented. The major steps on the way from semiconductor chip design, through module development, and to full current inverter operation are discussed, chosen solutions are explained, and results are presented. The main challenges include robust high current > 100 A GaN die, with low parametric shift because of repetitive unclamped switching tests up to 1600 V; driving 4 dies in parallel to obtain equal current sharing, the smooth waveform at needed current and obtaining low voltage overshoots on the gate and on the drain.
Industry Session
- Session name: Safety and Reliability
- Speaker: Kurt Smith, Ph.D., VP of Reliability and Qualification
- Title: Reliability of Gallium Nitride Technology for Energy Conversion
- Time: Wednesday, March 22, 2023, 4:20 p.m. – 4:45 p.m. ET
Abstract:
Understanding the reliability of GaN Devices and how that relates to the operational conditions is critical to choosing an appropriate device technology to meet the application requirements. The variety of GaN devices provides a wide range of potential robustness. This presentation will address the crucial aspects of reliability and reliability assessment to assess a technology on its fit to application needs through the evaluation of the VisIC high-reliability D3GAN technology and comparisons to other GaN technology.
