Reference number : GC-2017-Q2-00023, amendment number : , agreement type : G, recipient legal name : Liu, Yan-Fei (Queen’s University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Collaborative Research and Development Grants - Project, program name french : Subventions de recherche et développement coopérative - projet, program purpose english : Data centers are the backbone of global economic and consume an enormous amount of energy. U.S data_x000D_
centers consumed about 70 billion kilowatt-hours of electricity in 2014 and will double that amount by 2020._x000D_
An AC - DC rectifier converts the AC grid voltage to the motherboard of the data center to power the CPU,_x000D_
memory, network ports, etc. It contains two stages. The first stage is the Power Factor Correction (PFC) stage_x000D_
which converts the AC voltage to 400V DC and the second stage is a DC-DC converter that converts 400V to_x000D_
12V. It is very important to increase the efficiency of the AC - DC Rectifier._x000D_
The existing AC - DC rectifiers use MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) were_x000D_
developed 40 years ago. The performance of MOSFET has reached its theoretical limits. The new GaN switch_x000D_
(Gallium Nitride) is a revolutionary advancement in power semiconductor technology and can significantly_x000D_
improve the efficiency of power supplies. However, there is still a big technical gap between the existing GaN_x000D_
switch based designs and the optimum designs that could be achieved by GaN switches._x000D_
This project will focus on the PFC stage of the data center rectifiers. A half-bridge GaN switch module_x000D_
technology will be developed and employed in the bridgeless Boost converter to achieve 99% efficiency, which_x000D_
will only dissipate less than half of the loss of the MOSFET counterpart. This will enable the data center_x000D_
rectifier to meet the highest Titanium efficiency level of Energy Star 80 PLUS standard. The developed_x000D_
technology can also be used in the second stage of the data center rectifiers and improve its performance._x000D_
With the completion of this project, the Toronto design center of Murata Power Solutions will be able to design_x000D_
the most efficient data center power supply in the world and expand its sales volume in this market. GaN_x000D_
Systems will also demonstrate the full potential of their GaN switches used in the server as well as other power_x000D_
supplies. Therefore, the project will also increase the publicity and sales volume of GaN Systems._x000D_
In addition, 5 Highly-Qualified-Personnel (HQP) will be trained in this project., program purpose french : Data centers are the backbone of global economic and consume an enormous amount of energy. U.S data_x000D_
