项目摘要

In modern residential and commercial buildings today, electrical loads are growing fast to be more native direct-current (DC) loads, including computers, smartphones, cameras, smart-home devices, LED lightbulbs, information screens, televisions, microwave oven, and other appliances, etc. To optimize efficiency and maintain the reliability of the electric grid, DC sources and energy buffers, such as solar energy and other renewable energy sources, vehicle batteries, and other separate batteries are integrated at an unprecedented rate. While these electrical components are direct-current (DC) in nature, they still need to interface with the legacy alternating-current (AC) power line in our home and building, leading to inefficiencies in power delivery (10%-30% loss in total power consumption), space utilization, and added 10%-15% overall system cost for many AC-DC adapters. In addition, AC distribution at 110-220 volts in commercial buildings and households also poses a safety concern especially for children as AC wall outlets and cords are responsible for 15% and 63% of injuries, respectively, in children aged 12 years and younger. The goal of this integrated research and education career development is to facilitate faster developments and increase adoption of DC micro-/nano-grids for more efficient DC distribution in residential and commercial use in a More-DC world, by realizing a next-generation integrated hybrid DC-DC power converter family with demonstrations for multiple important applications. The converters are designed to achieve superior efficiencies, smaller sizes, and lower system cost that can reduce the number and impact of inefficient AC-DC conversions. The research program, positioned at the boundary of integrated circuits and power electronics, aims at fundamental advancements in converter technologies, integrated circuit designs, integrated packaging, and system integration for DC power management and delivery, applicable in billions of home and office devices. The research outcomes can be applied and create positive impacts in improving efficiency and density of power management and delivery in many applications, including mobile battery chargers, mobile computing, data centers, DChomes/DC-buildings, automotive vehicles, motor drive, and LED lightings. A significant part of the research program is to integrate fundamental research with education in the area of integrated power electronics and energy efficiency through training and involvement of US San Diego graduate and undergraduate students, specific outreach modules that will engage and attract K-12 students and the general public to this important STEM area, and teaching activities that integrate research topics and findings in the curriculum. To achieve the research goal, the objectives of this CAREER proposal are to: (1) investigate and implement scalable integrated converters with high input voltage and large conversion ratio based on a novel single-inductor multi-synchronous stage (SIMS) DC-DC converter architecture that can efficiently provide large conversion ratios from high input voltages in order to minimize the number and impact of AC-DC conversions, (2) study and design integrated packaging procedures using integrated silicon capacitors to fundamentally reduce distribution loss and improve the system efficiency and power density, (3) generalize the median-average analysis (MAA) methodology, and use it to provide more accurate, intuitive model and control of hybrid DC-DC converters in order to bridge key knowledge gaps in understanding core operations and control of hybrid converters, (4) demonstrate and evaluate the feasibility of a DC nano-grid using a single AC/DC converter to supply multiple DC loads through the integrated converter prototypes developed in this project, and (5) demonstrate the integrated power delivery systems in a number of example applications, including battery charger, mobile and highperformance computing, and DC-home/DC-building power distribution. This comprehensive effort enables important innovations and fundamental advances to push the boundary of two areas, integrated circuits (with high input voltages, high power and current density) and power electronics (with large direct step-down, and integrated hybrid architecture).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在当今的现代住宅和商业建筑中，电力负载正在快速增长，越来越多的是原生直流（DC）负载，包括计算机、智能手机、相机、智能家居设备、LED灯泡、信息屏幕、电视、微波炉和其他电器等。为了优化效率和保持电网的可靠性，直流电源和能量缓冲，如太阳能和其他可再生能源，汽车电池和其他独立的电池以前所未有的速度集成。虽然这些电子元件本质上是直流电（DC），但它们仍然需要与我们家庭和建筑物中的传统交流（AC）电力线连接，导致电力传输效率低下（总功耗损失10%-30%），空间利用率低下，并且许多AC-DC适配器的总体系统成本增加了10%-15%。此外，商业建筑和家庭中110-220伏的交流配电也引起了安全问题，特别是对儿童来说，因为12岁及以下儿童的交流墙壁插座和电源线分别造成15%和63%的伤害。这一综合研究和教育事业发展的目标是通过实现下一代集成混合DC-DC电源转换器系列，并为多种重要应用进行演示，促进直流微/纳米电网的更快发展，并增加直流微/纳米电网在更多DC世界中用于住宅和商业用途的更高效直流配电的采用。该转换器旨在实现更高的效率、更小的尺寸和更低的系统成本，从而减少低效AC-DC转换的数量和影响。该研究项目定位于集成电路和电力电子的边界，旨在实现转换器技术、集成电路设计、集成封装和直流电源管理和传输系统集成的基本进步，适用于数十亿家庭和办公设备。该研究成果可以应用于许多应用，并对提高电源管理和传输的效率和密度产生积极影响，包括移动电池充电器、移动计算、数据中心、DChomes/ dc建筑、汽车、电机驱动和LED照明。该研究计划的一个重要部分是通过对美国圣地亚哥研究生和本科生的培训和参与，将综合电力电子和能源效率领域的基础研究与教育结合起来，具体的外展模块将吸引K-12学生和公众参与这一重要的STEM领域，以及将研究主题和发现整合到课程中的教学活动。为了实现研究目标，本CAREER提案的目标是：(1)研究并实现基于新型单电感多同步级（SIMS） DC-DC转换器架构的高输入电压和大转换比的可扩展集成转换器，该架构可以从高输入电压有效地提供大转换比，以最大限度地减少AC-DC转换的数量和影响；(2)研究和设计采用集成硅电容器的集成封装流程，从根本上降低配电损耗，提高系统效率和功率密度；(3)推广中均值分析（MAA）方法，并利用其提供更准确、直观的混合DC-DC变换器模型和控制，以弥合理解混合变换器核心操作和控制的关键知识空白；(4)演示和评估使用单个AC/DC转换器通过本项目开发的集成转换器原型提供多个直流负载的直流纳米电网的可行性；(5)在许多示例应用中演示集成电力输送系统，包括电池充电器，移动和高性能计算，以及DC-家庭/DC-建筑配电。这一全面的努力使重要的创新和基础进步能够推动两个领域的边界，集成电路（高输入电压，高功率和电流密度）和电力电子（具有大直接降压和集成混合架构）。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
