With the exponential growth in internet / wireless applications, more and more servers, including data centers, data storage, cloud storage and others, have been built to process the ever-increasing network traffic. Multiple Point of Load power supplies are used in the motherboard to provide regulated voltages to CPU (Central Processing unit), GPU (Graphic Processing Unit), RAM (Random Access Memory), and other digital circuits. It takes long time to design such a power supply system to meet the requirement. In a lot of cases, the design time for the power system becomes the bottle neck in the product development schedule. Therefore, it is very important to reduce the power system design time in order to reduce the product development time.**In this research program, a radically new power architecture will be proposed to significantly reduce the power system design time. With the new architecture, feedback signals between the Power Processing Cell (PPC) and Central Control Unit (CCU) will be communicated wirelessly without any Printed Circuit Board (PCB) tracks. Three major benefits can be obtained. The first benefit is much shorter power system design time because all the features of the power system can be programmed with software and no hardware links (i.e. no PCB tracks) between PPC and CCU are needed. The second benefit is lower system cost because standardized PPC and CCU can be designed and made in large quantity, which can reduce the unit cost. The third benefit is extreme flexibility because the functions of the power system can be changed with software and no hardware change is needed.**This research program will develop all the technologies to implement the proposed power architecture with wireless feedback control, such as partitioning of PPC and CCU, wireless communication strategy between PPC and CCU, and minimum data transmission technologies to ensure highly reliable operation of the power systems. An experimental power system will also be built to demonstrate the feasibility and advantages of the new power architecture. It is expected that several fundamental patents in the wireless feedback control field will be filed through PARTEQ Innovation (commercialization / patent division of Queen's University) to protect the intellectual property.**In this research program, four PhD students, five master students and ten undergraduate students will be trained in areas of switching power supplies, digital control technology, wireless feedback control, analysis and design of digital feedback systems, firmware and software programming skills, as well as server power system requirement, hardware debugging skills. They will play very important roles in developing and commercializing the new power architecture for next generation server and data center power systems.**Power system for server and data center is a multi-billion dollar business. During the transformation from old wired architecture to the new wireless architecture, new business opportunities will be created for Canadian companies and businesses. The HQP trained in this research program will help Canadian power design centres lead the world in developing next-generation power systems with wireless feedback control. Canada will become an international leader in this field with this revolutionary new technology, which will bring job creation and a competitive edge for Canada in this multi-billion dollar industry.

随着Internet /无线应用程序的指数增长，已经构建了越来越多的服务器，包括数据中心，数据存储，云存储等，以处理不断增加的网络流量。主板中使用多点负载电源为CPU（中央处理单元），GPU（图形处理单元），RAM（随机访问存储器）和其他数字电路提供监管电压。设计这样的电源系统需要很长时间才能满足需求。在许多情况下，电源系统的设计时间成为产品开发计划中的瓶颈。因此，减少电源系统设计时间以减少产品开发时间非常重要。借助新的体系结构，将无线通信电源处理单元（PPC）和中央控制单元（CCU）之间的反馈信号，而无需任何印刷电路板（PCB）轨道。可以获得三个主要好处。第一个好处是电源系统设计时间较短，因为电源系统的所有功能都可以使用软件编程，并且不需要PPC和CCU之间的硬件链接（即没有PCB轨道）。第二个好处是系统成本较低，因为标准化的PPC和CCU可以大量设计和制造，这可以降低单位成本。第三个好处是极高的灵活性，因为可以通过软件更改电源系统的功能，并且不需要更改硬件。还将构建实验电源系统，以证明新电源架构的可行性和优势。预计将通过Parteq Innovation（商业化 /皇后大学的商业化 /专利部门）提交无线反馈控制领域的几项基本专利，以保护知识产权。需求，硬件调试技能。他们将在开发和商业化下一代服务器和数据中心电源系统的新电源体系结构中发挥非常重要的作用。**服务器和数据中心的电源系统是一项数十亿美元的业务。在从旧有线体系结构到新的无线体系结构的转型期间，将为加拿大公司和企业创建新的商机。在该研究计划中培训的HQP将帮助加拿大电力设计中心带领世界开发具有无线反馈控制的下一代电力系统。加拿大将通过这项革命性的新技术成为该领域的国际领导者，这将为这一数十亿美元的行业带来创造就业机会和竞争优势。
