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.
Panelist: Alex Lidow, CEO and Co-founder, Efficient Power Conversion
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.

GaN Transistors and ICs for 48 – 12 V Bi-Directional Converters for Mild Hybrid Vehicles
Speaker: Alex Lidow, Ph.D., CEO and Co-Founder of Efficient Power Conversion
Recent advances in automotive powertrain technology have accelerated the use of a dual 48 V/12 V bus architecture in mild hybrid vehicles, which can provide an 8-15% fuel consumption reduction. The availability of a 48 V bus also enables support of heavier loads like air-conditioning, faster heating of cabin, and faster, smoother starting with the use of 48 V Li-ion batteries. GaN-on-Si power devices are the best-suited semiconductors for this application as will be shown in this talk.

Magnetic resonance technology is the key to ubiquitous implementation – enabling large surface area transmission, spatial freedom for placement of receiving devices, and the ability to power multiple devices simultaneously.
The popularity of highly resonant wireless power transfer is increasing rapidly, particularly for applications targeting large power transmitting surface areas, with the capability to place receiving devices anywhere on the surface, and the ability to simultaneously power (or charge) multiple devices placed on the surface. The end applications are varied and evolving quickly from cell phone charging to powering handheld tablets and laptop computers. Delivering up to 33 W supports all of these applications.
At the members meeting attendees learned about next-generation wireless power technology – including current and near-future deployments – and heard from leaders such as Alex Lidow from the semiconductor space as well as consumer electronics, robotics, AR/VR, and healthcare industries, to name a few.
AirFuel Alliance’s mission is to bring a diverse base of interoperable products to the global market that deliver the best wireless charging experience for consumers. The organization membership is made up of leading technology and consumer electronics companies. Its board of directors includes representatives from Dell, Duracell, Energous, EPC, ONSemiconductor, PowerSphyr, Qualcomm, Samsung Electronics, Starbucks and WiTricity.
