The Ascent of GaN

Speaker: Alex Lidow, Ph.D., CEO and Co-founder, EPC

After more than 13 years of mass production, GaN-on-Si has gained widespread acceptance as the successor to the aging silicon MOSFET for voltage ranging between 40 V and 650 V. What, therefore, are the variables controlling the rate of growth of GaN power devices. We will dig into the experience, and lessons learned from the power MOSFET as well as the recent experiences with GaN in applications ranging from DC-DC conversion to motor drives and lidar in markets such as space, automotive, enterprise computing, and consumer products.

Panel Discussion: SiC and GaN Power Devices’ Reliability and Quality

Panelists: Doug Bailey, Vice President Marketing & Applications Engineering, Power Integrations; Anup Bhalla, Chief Engineer, Power Devices, Qorvo; Thierry Bouchet, CEO, Wise Integration; Alex Lidow, CEO, Efficient Power Conversion; Guy Moxey, Senior Director Power Products, Wolfspeed

WBG semiconductors have helped improve the performance of power systems and cut down on the cost of their parts. Failure rates in the parts-per-billion level are necessary to compete in markets with stricter standards. The primary reliability issues that face WBG semiconductors like SiC and GaN, as well as the corresponding quality standards for high-performance designs in several mission-critical applications, will be covered in this panel discussion. Aspects including material quality, thermal management, high-power operation, qualification testing and long-term performance will be covered by each panelist.

GaN Evolution – The Present and Future

Keynote Speaker: Alex Lidow, Ph.D., CEO and Co-Founder of Efficient Power Conversion

Power electronics has been dominated by MOSFETs for almost 40 years and by the year 2000, MOSFETs had hit their theoretical performance limit and its progress had been slowed down with the major focus on pricing. GaN provides significant opportunities for designers to achieve higher performance by an order of magnitude better than their aging MOSFET ancestor. This has enabled users to significantly reduce costs, improve efficiency, shrink product size, offer new capabilities, and gain market share against their competitors. In this keynote speech, learn how GaN is revolutionizing power management applications such as motor drives for drones, e-bikes, scooters and power tools; DC-DC converters and solar applications.

Understanding Why Cost of Energy is the Key to Sustainability

Presenter: Alex Lidow, Ph.D., CEO and Co-Founder of Efficient Power Conversion

Developing economies struggle to build energy infrastructure to support industry and bring electricity to far-flung villages. At the same time, industrialized economies are straining to balance conflicting demands for more power while decreasing the environmental impact. Finding ways to meet the rising demand for energy without plundering natural resources and aggravating climate change poses one of this century’s most significant global challenges. In this talk, we will link the true cost of energy to sort out real versus futile efforts to improve energy efficiency and show that wide bandgap semiconductors, such as gallium nitride (GaN), enable significant improvements in energy efficiency.

One way to tell when a new technology has passed the tipping point of adoption is by the voices advocating the status quo. The more conservative voices tend to cite older information that, given the fast change of trajectory that occurs at a tipping point, can lead to poor decisions for new designs.
