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项目旨在研究和开发基于分布式光伏串级最大功率点跟踪（MPPT）的模块化太阳能转换系统的新型高效DC-DC转换器。这项工作将与加拿大工业伙伴Solar Earth Technologies合作进行。公司专门从事电气化道路的开发和销售，电气化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化为分布式太阳能发电机。****太阳能公路在大规模太阳能发电中广泛应用的技术挑战之一在于太阳能系统的遮阳。具有MPPT控制的DC-DC电力电子变换器是光伏系统在遮阳条件下获得高收获效率的关键。传统的DC-DC变换器是基于MPPT集中控制。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上运行，这通常不是每个单独光伏模块的最大功率点。****这个NSERC参与资助项目的目标是研究分布式基于mpp的模块化太阳能转换系统，该系统可以为每个光伏模块执行独立的MTTP，并将提高光伏阵列的整体太阳能发电量和转换效率。UBC团队将进行新的DC-DC转换器和分布式MPPT控制的设计和原型制作。该研究项目将有助于加拿大清洁能源技术的发展，以实现大规模的太阳能发电、转换和利用，提高效率，降低能源成本
