Analysis and Design of High Efficiency, High Conversion Ratio, DC-DC Power Converters
CU Scholar, 2013Co-Authors: Costinett, Daniel JesseAbstract:In 2010, more than 2% of all electricity generated in the United States was used to power data centers. Estimates indicate that as many as 85% of data centers constructed prior to 2006 expend more than three times as much electric power on cooling and inefficient conversion than on powering the Server hardware itself. One key contributor to the poor energy efficiency in these data centers is power distribution architectures characterized by many cascaded and inefficient power converters. Though the architectures in these data centers vary greatly, they each stand to benefit significantly from a well-designed, highly efficient power converter capable of stepping down the high DC voltages generated in AC rectification to the low DC voltages capable of being distributed across the Server Motherboard. The design of this converter has unique requirements for the power electronics designer, including constraints on form factor, efficiency, and control. This thesis considers the requirements imposed by the data center application to motivate the analysis and design of high efficiency, high step-down, high frequency DC-DC converters for data centers and other applications

using a hybrid ldo regulator and a switching regulator circuit to reduce the power consumption in the light load operation of a Server Motherboard
Canadian Conference on Electrical and Computer Engineering, 2015Co-Authors: Yingwen Bai, Chenghung LinAbstract:In this paper we propose a hybrid LDO regulator and switching regulator circuit design that uses an LDO regulator instead of a switching regulator to operate in light load. By means of this method our design reduces the power consumption of a switching regulator in light load at the input terminal, and then reduces the power consumption of the Server Motherboard during the operation. This design includes a microcontroller Unit (MCU) which is able to initialize, detect, judge and control both regulator operations. In addition, the MCU controls both the LDO regulator and the switching regulator in order to transition between light load and heavy load.

multi robot collaborative assembly research for 3c manufacturing taking Server Motherboard assembly task as an example
International Conference on Intelligent Robotics and Applications, 2019Co-Authors: Yanpu Lei, Jiawei Luo, Haitao ZhangAbstract:In the multi-robot collaborative manufacturing, such as the Server Motherboard assembly task in the 3C industry, the characteristic of the operating process and the uncertainty of the assembly environment make this problem difficult to be solved in an efficient way. This paper addresses the key points of this problem. Firstly, a series of end effectors for 3C assembly operation is designed. After analyzing precision and scope for different steps in the assembly process, the positioning systems with different precision and scope are designed and are chosen for better performance in different operations. Finally, compliant control is introduced in the inserting process where the positioning system does not perform well to further increase the success rate. Experiments illustrate the superiority of our ideas. Due to its convenience and generality, the present approach can be expected to apply to more general industrial scenarios.
