GaN power electronics converters for hybrid renewable energy systems

全球范围内正在共同努力，以提高可再生能源发电的比例，并建设新的分散式智能电力基础设施，即“微电网”。微电网的成功关键取决于混合电力系统的发展，该系统包括风力涡轮机、太阳能电池板、电池、燃料电池和电力电子转换器。拟议的研究计划侧重于开发新的基于氮化镓(GaN)的电力电子转换器拓扑结构，该拓扑结构可显著降低损耗并提高混合可再生能源系统的功率密度。这项研究的创新之处在于所提出的替代现有变流器拓扑和控制技术的方案具有独特性。主要的重点是设计最少的元件、高效和非常高的开关电路拓扑和数字控制技术，以实现经济高效和紧凑的功率转换器设计。将对HQP进行培训，并开发下一代电力电子技术，用于设计高效、紧凑和具有成本效益的具有储存能力的可再生能源系统。

A concerted effort is being made worldwide to generate a larger proportion of energy from renewable energy sources and to build new decentralized smart power infrastructures or 'microgrids.' Energy storage technologies play a critical role in efficient microgrid operation. The success of microgrids depends critically upon the development of hybrid power systems comprising wind turbines, solar panels, batteries, fuel cells and power electronics converters. The proposed research program focuses on development of new gallium nitride (GaN) based power electronics converter topologies with significantly reduced losses and increased power density for hybrid renewable energy systems. The innovative character of the proposed research lies in the uniqueness of the proposed alternatives to existing converter topologies and control techniques. The main emphasis is to devise minimum-components, highly-efficient and very-high switching circuit topologies and digital control techniques that enable cost-effective and compact power converter designs. The proposed research exemplifies academic significance and industrial importance. HQP will be trained and next generation power electronics technologies will be developed for practical use in designing efficient, compact and cost-effective renewable energy systems with storage capability.
