Single-stage Step-up Photovoltaic Maximum Power Extractor for A Microwave Heating System in Carbon Soot Removal

截至2020年，加拿大排放了近3万吨黑碳，其中运输和重型移动设备是黑碳排放的最大来源。传统上，从发动机油中过滤碳烟是非常困难和不经济的。加拿大承诺到2030年将其温室气体（GHG）排放量从2005年的水平减少40-45%，并确保黑碳去除过程能够在对环境影响最小的情况下高效实现，因此转向绿色电力解决方案来处理黑碳烟尘去除至关重要。光伏（PV）能源提供了一种有吸引力的替代绿色能源。在OMTEC公司的支持下，拟议的研究项目的目标是开发一种高效的光伏能源转换方案，用于微波加热技术，以消除柴油发动机汽车旧发动机油中的碳烟。具体而言，本研究项目将：(1)开发具有高电压增益的单级光伏最大功率点跟踪器，用于与磁控管接口作为微波能量源；(2)研究有效去除碳烟的微波热能的最佳量；(3)开发能量管理控制方案，以最大限度地提高PV辐照水平范围内PV-微波能量转化率。(4)在真实的微波能量产生环境中开发和测试概念验证的硬件电力电子原型。由于拟议的项目侧重于开发清洁的碳烟去除工艺，因此开发和采用更高效和清洁的柴油动力汽车将大大减少温室气体，并为加拿大人的健康带来好处。

As of 2020, almost 30 kilotonnes of black carbon were emitted in Canada, with transportation and heavy mobile equipment representing the largest source of black carbon emission. Filtration of carbon soot from the engine oil is traditionally very difficult and uneconomical. With Canada committed to reduce its greenhouse gas (GHG) emissions by 40-45% from 2005 levels by 2030 and to ensure that the black carbon removal process can be achieved efficiently with minimal environmental impact, it is essential to shift towards green power solutions for processing black carbon soot removal. Photovoltaic (PV) energy provides an attractive alternative green power source. Supported by OMTEC Inc, the objective of the proposed research project is to develop a highly power efficient PV energy conversion scheme for use in microwave heating technology for eliminating carbon soot in diesel engines automobiles' used engine oil. To be specific, this research project will: (1) develop a cost-effective single-stage PV maximum power point tracker with high voltage gain capability for interfacing with the magnetron for use as the microwave energy source, (2) investigate the optimal amount of microwave heat energy for effective carbon soot removal, (3) develop an energy management control scheme to maximize the PV-to-microwave energy conversion rate for a wide range of PV irradiation levels, and (4) develop and test proof-of-concept hardware power electronic prototypes in a real microwave energy generation environment. As the proposed project focuses on the development of a clean carbon soot removal process, the development and adoption of more efficient and clean diesel powered automobiles will reduce GHG significantly and result in health benefits to Canadians.
