A high power density microwave energy power source for carbon soot processing in diesel engine application

柴油发动机的碳排放是汽车污染的主要来源，对环境有害。众所周知，柴油机燃烧排放的碳烟颗粒部分混合在运行和使用过的内燃机油中。根据《巴黎协定》，加拿大承诺到2030年将其温室气体排放量(GHG)在2005年的基础上减少30%。为了通过减少碳足迹来应对气候变化，拟议的研究项目的目标是研究和开发一种清洁、高功率效率和环保的微波技术，用于处理汽车应用中运行和使用的发动机油中的碳烟。特别是，拟议的项目将开发一种新型的高功率密度功率转换电路，能够高效地产生微波能量(在数千MHz范围内)，用于消除碳烟。在微波能量发生器中，高压电源是关键部件。因此，需要具有很高电压转换比的功率转换电路。提出的功率转换电路将具有非常大的升压转换比，并具有无损耗开关行为，以最大化电路效率。该项目的成功成果将有助于OMTEC保持其在柴油发动机应用油加工尖端技术开发方面的领先地位。除了技术进步外，拟议的研究项目还将为学生提供机会发展强大的分析技能，以设计新的电力电子电路，并在微波发电的概念验证电力电路原型方面获得丰富的硬件测试经验。所有设计的电力转换电路概念所开发的硬件原型将在约克大学先进电力电子可持续能源研究实验室进行测试。

Carbon emissions from diesel engines are a major source of automotive pollution and are harmful to the environment. It is known that the diesel combustion exhaust releases carbon soot particle, which is partially mixed in operational and used engine oil. Under the Paris Agreement, Canada is committed to reducing its greenhouse gas emissions (GHG) by 30% below 2005 levels by 2030. To combat climate change by reducing the carbon footprint, the objective of the proposed research project is to investigate and develop a clean, high power efficiency and eco-friendly microwave technology for processing carbon soot in the operational and used engine oil in automotive application. In particular, the proposed project will develop a novel high power density power conversion circuit that is capable of generating microwave energy (in the range of thousands of MHz) efficiently for use in carbon soot elimination. In a microwave energy generator, the key element is the high voltage power supply. Hence, power conversion circuit with a very high voltage conversion ratio is required. The proposed power conversion circuit will feature very large step-up voltage conversion ratio with loss-less switching behavior to maximize the circuit efficiency. Successful outcomes from this project will help OMTEC to maintain its position as a leader in the development of cutting edge technology for the oil processing of diesel engine application. In addition to technology advancement, the proposed research project will provide opportunities for students to develop strong analytical skills to devise novel power electronic circuits, and to gain extensive hardware testing experience in proof-of-concept power circuit prototypes for microwave energy generation. The developed hardware prototypes of all the devised power conversion circuit concepts will be tested at the Advanced Power Electronics Laboratory for Sustainable Energy Research at York University.
