The recent adoption of direct current (DC) powered equipment (computers, telecoms, data centers, consumer electronics) has increased global electricity consumption by 27% over the past decade. Since power converters (AC/DC and DC/DC) are required to supply DC equipment, their conversion efficiency plays a critical role in saving energy and reducing carbon emission from generation plants. This is extremely important in emerging DC buildings and the rapidly expanding telecom/IT infrastructure, where the majority of the DC power is consumed and must be supplied in a cost effective and efficient manner.The objective of the collaboration between Dr. Ordonez at UBC and Alpha Technologies is to develop high efficiency power conversion technology to support DC infrastructure in order to consolidate and improve power conversion on large-scale, modular applications. Alpha Technologies Ltd., one of the top high-tech employers in BC, is a leading company in powering solutions integration for communication, medical and industrial environments.This R&D project combines novel power devices (Gallium nitride), advanced soft-switching topologies, and control architectures with complex analysis and simulation techniques in order to reduce the size, improve efficiency, and cut power losses of DC powering systems by 40%. With the incorporation of novel technology, the expanding Telecom, IT infrastructure, and emerging DC buildings will substantially benefit from reduced energy consumption and costs. The project aligns with the government of Canada's initiatives to promote energy efficiency and clean energy technology.

最近直流（DC）供电设备（计算机，电信，数据中心，消费电子产品）的采用使全球电力消耗在过去十年中增加了27%。由于电力变换器（AC/DC和DC/DC）需要为直流设备供电，因此其转换效率在发电厂节能和减少碳排放方面起着关键作用。这在新兴的直流建筑和快速发展的电信/IT基础设施中非常重要，其中大部分直流电源都是消耗的，必须以具有成本效益和高效的方式提供。UBC的Ordonez博士和Alpha Technologies之间的合作目标是开发高效率的电源转换技术，以支持直流基础设施，从而巩固和改善大规模的电源转换，模块化应用。阿尔法科技有限公司，BC省最大的高科技雇主之一，是一家领先的通信、医疗和工业环境电源解决方案集成公司，该研发项目将新型功率器件（氮化镓）、先进的软开关拓扑和控制架构与复杂的分析和仿真技术相结合，以缩小尺寸，提高效率，并将直流电源系统的功率损耗降低40%。随着新技术的引入，不断扩大的电信、IT基础设施和新兴的DC建筑将从降低的能耗和成本中受益。该项目与加拿大政府促进能源效率和清洁能源技术的举措保持一致。
