Title: Integration of Gallium Nitride in Power Applications: Achievements and Challenges
Abstract: The U.S. Department of Energy has recognize the opportunity to reduce dramatically usage of electricity in homes and businesses through adoption of variable speed motor control. An estimated 535 x 1012 BTU of energy could be saved annually in the US through use of variable speed drive (VSD) in home appliances and an additional 461 x1012 BTU’s when commercial appliances are considered. In total, this is the equivalent of reducing annual release of greenhouse gases due to the usage of 5.5 million short tons of coal.Today VSD are inverterized based on state of the art (SOA) silicon based power solution using either 6 FREDFET power MOSFET or 6 IGBT/FRD pairs together with a gate driver IC capable to drive all 6 switches as a voltage source. The proposed concept is to leverage existing 600V normally off (e-mode) CoolGaNTM switches for use in our VSD “power stages” which feature package integration of 6 GaN HEMT. The reverse recovery performance of CoolGaNTM, provides substantial advantage in term of turn on Loss at full and partial load enabling > 50% reduction in power loss. For successful adoption in motor control, 3 elements of a GaN-based solution are required:
a.) a low cost driver IC which provides current source drive signal as the CoolGaNTM gate is current driven, and protect functions (control slew rate to <5V/ns). The IC must also cost no more than existing low cost voltage source IC’s used with silicon. In this paper, we will describe the proposed solution to realize this IC based on Junction Isolated level shifting technology. b.) A Competitive cost GaN devices. For RDS(ON) values in the 1 ohm range CoolGaNTM die are 5x to 6X times smaller than FREDFET’s so that even with higher wafer cost per area the GaN die cost will be lower than silicon. On top, the lateral nature of the GaN device brings the potential further advantage to integrate monolithically the 6 GaN switches into one die. The paper, will show the challenge to do so, due to the back gating of the high side switch by the low side switch, due to the common silicon substrate, and the proposed remedy to this problem. c.) A low cost surface-mount package solution achieved through the simplification of the 12×12 mm QFN package due to the monolithically integrated GaN switches, which reduces the number of components in the package from 7 (or 13 in case of IGBT) to 2.

Title: Emerging eT&D Grids: Energy Storage, Electrification, and the Increasing Role of Power Electronics
Abstract: Emerging electronic transmission and distribution (eT&D) grids will evolve rapidly accommodating the changes in generation mix and load profile that are associated with increasing renewable and distributed generation, electrification and bidirectional power flows. For eT&D grids to operate reliably with a high degree of autonomy, there is a greater need for energy storage systems and intelligent power conversion systems with advanced circuit topologies and high speed communication infrastructure. Current challenges for the future eT&D grids include limited scale of energy storage deployments along with low penetration of power electronics in the current grid infrastructure. As we look into a future with 70-80% renewables in the generation mix and higher amounts of dc loads including electric vehicles and appliances, the load profile and operational aspects of the grid will experience changes that are not well forecast. In this presentation, I will review state of eT&D grid development, expected developmental pathways, and projections for eT&D grid in the distant future.

Title: Ultra High Power Density Demands 99% Efficiency and 99% Duty Ratio
Abstract: Recent technology progress demonstrated effective ways of obtaining 99% power efficiency. The near adiabatic power conversion technology, for instance, needs no dedicated thermal management. Yet ultra-high power density has eluded many designs. The most recent technology trend in power conversion, particularly for dc-dc, suggests a significant increase in power density is within reach. Ultra-high power density in commercial products demands a 99% efficiency and a virtual full duty ratio (say, 99%). The path forward requires a systematic approach in leveraging distributed low-profile packaging, minimum inductive storage, capacitive energy transfer, partial power processing, integrated WBG devices, modularity, and scalability. It is anticipated that the power electronics industry will achieve an-order-of-magnitude improvement in achievable power density within the coming years.

Title: Co-Design: A Paradigm Shift to Enable Next-Generation Power Modules
Abstract: The Army is moving to a more electrified force for an increasing number of applications including vehicles, renewables, tactical energy networks, communications, and weapons systems. Current power electronics devices are unable to realize their full potential due to the challenges of standard packaging including thermal dissipation, reliability, and parasitic inductance. As technology advances, the electrical, thermal, and reliability needs of these systems must be simultaneously accounted for due to the need for more power in smaller units with no loss in performance. Unfortunately, most research has focused on solving only one technical challenge: a better heat sink, a better circuit design or a more reliable material. When thermal design is treated as a discrete step and not addressed until the end of development, systems become large, overly complex, and inefficient. This presentation will introduce the concept of co-design, a paradigm shift which moves away from the siloed approach to design and transitions into multi-disciplinary design to enable holistic improvement for next generation power electronics. The presentation will cover the current thermal and packaging challenges associated with power modules and will define the three key enabling capabilities to enable future power modules and next-generation cooling solutions: (1) parametric modeling tools, (2) additive manufacturing and (3) transient thermal mitigation.
Bio: Dr. Lauren Boteler leads the thermal and packaging research programs as part of the Advanced Power Electronics group at the U.S. Army Research Laboratory (ARL). She received her PhD degree in mechanical engineering from the University of Maryland. Her work at ARL, beginning in 2005, has included electronics packaging and thermal management solutions for a wide range of Army applications. Her focus is on design tool development and package integrated thermal solutions including 3D chip stacking, power electronics, laser diodes, double side cooling, and phase change materials. More recently, she has initiated a research program in Advanced Power Electronics Packaging and Thermal Management which defined the four main challenges and opportunities of power electronics packaging: co-engineering/co-design, transient thermal mitigation, additive manufacturing, and high-voltage packaging. She is an adjunct professor at Johns Hopkins University and was awarded the 2018 ASME EPPD Woman Engineer of the Year award for her contributions to the electronics packaging community.

Title: Power and Energy for the Future U.S. Army
Abstract: The U.S. Army recently established the Army Futures Command to develop revolutionary technology for military applications. Intelligent power and energy architecture will be essential as the Army’s needs for mobile power continue to grow. The Army has achieved considerable success in improved fuel consumption by applying the principles of smart grids to battlefield electric power generation. A further level of sophistication must be implemented to such grid design because the number and power ratings of power generators and loads may vary often over time and location. Areas of opportunity for such power and energy technology include advanced power sources, including renewables, generators and batteries, advanced power conditioning devices and more sophisticated thermal management.
