This Engage project aims at the research and development of new high efficiency DC-DC converters for distributed PV string-level Maximum Power Point Tracking (MPPT) based modular solar-energy conversion system. The work will be conducted in collaboration with Canadian industrial partner, Solar Earth Technologies. The company specializes in the development and marketing of the electrified roadways which embed the road surface with a solar photovoltaic (PV) system to convert the conventional concrete and asphalt based roads into distributed solar power generator.****One of the technology challenges for the solar-powered roadways to be widely adopted in large-scale solar energy generation resides in the shading in solar systems. A DC-DC power electronic converters with MPPT control is critical for the PV system to obtain high harvesting efficiency in the shading condition. The conventional DC-DC converter is based on centralized MPPT control. The main drawback of the centralized converter is that the complete PV field is operated at one overall maximal power point which is usually not the maximum power point for each individual PV module. ****The objective of this NSERC Engage Grant project is to investigate the distributed MPPT-based modular solar-energy conversion system which can perform an independent MTTP for each PV module and will improve the overall solar power yield and conversion efficiency of PV arrays. The UBC team will carry out the design and prototyping of the new DC-DC converters and distributed MPPT control. The research project will contribute to Canadian clean energy technology development to enable large-scale solar energy generation, conversion and utilization with increased efficiency and reduced energy cost.**

该Engage项目旨在为基于分布式光伏组串级最大功率点跟踪（MPPT）的模块化太阳能转换系统研发新型高效DC-DC转换器。这项工作将与加拿大工业合作伙伴 Solar Earth Technologies 合作进行。该公司专门从事电气化道路的开发和营销，该道路在路面上嵌入太阳能光伏（PV）系统，将传统的混凝土和沥青路面转变为分布式太阳能发电机。****的技术挑战之一大规模太阳能发电广泛采用的太阳能道路在于太阳能系统的遮阳。具有MPPT控制功能的DC-DC电力电子转换器对于光伏系统在遮光条件下获得高收集效率至关重要。传统的DC-DC转换器基于集中式MPPT控制。集中式转换器的主要缺点是整个光伏场在一个整体最大功率点运行，该最大功率点通常不是每个单独光伏模块的最大功率点。 ****本NSERC Engage Grant项目的目标是研究基于分布式MPPT的模块化太阳能转换系统，该系统可以为每个光伏组件执行独立的MTTP，并将提高光伏阵列的整体太阳能发电量和转换效率。 UBC 团队将进行新型 DC-DC 转换器和分布式 MPPT 控制的设计和原型制作。该研究项目将为加拿大清洁能源技术的发展做出贡献，以实现大规模太阳能发电、转换和利用，提高效率并降低能源成本。 **
