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

截至二零二零年，加拿大排放近30千吨黑碳，其中运输及重型移动的设备为最大黑碳排放源。 从发动机油中过滤碳烟传统上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%，并确保在最小环境影响的情况下有效实现炭黑去除过程，因此必须转向绿色电力解决方案来处理炭黑去除。 光伏（PV）能量提供了一种有吸引力的替代绿色电源。 在OMTEC公司的支持下，拟议研究项目的目标是开发一种高功率效率的光伏能量转换方案，用于微波加热技术，以消除柴油发动机汽车用机油中的碳烟。 具体而言，本研究项目将：（1）开发具有高电压增益能力的成本有效的单级PV最大功率点跟踪器，用于与用作微波能量源的磁控管接口，（2）研究用于有效去除碳烟灰的微波热能的最佳量，（3）开发能量管理控制方案，以在宽范围的光伏辐照水平下最大化光伏到微波的能量转换率，以及（4）在真实的微波能量产生环境中开发和测试概念验证硬件功率电子原型。 由于拟议项目的重点是开发一种清洁的碳烟灰去除工艺，开发和采用更高效、更清洁的柴油动力汽车将大大减少温室气体，并为加拿大人带来健康益处。

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.
