Power Electronic Converters

运输业排放的温室气体占加拿大温室气体排放量的四分之一。联邦法规规定，2030年销售的所有新车中，至少有60%必须是零排放汽车(ZEV)，然后在2035年上升到100%。鉴于2021年在加拿大销售的汽车中只有约5%是电动汽车，电动汽车内部和基础设施层面的重大创新都是迫切需要的。CRC第二期研究计划的目标是解决电动汽车(EV)大规模采用的两个关键障碍：1)电动汽车电池组的实际性能有限，这影响了电动汽车的定价、寿命和寒冷气候下的行驶里程；2)缺乏廉价、模块化和紧凑的直流快速充电基础设施，这对实现城际和乡村旅行至关重要。这项为期五年的计划分为三个免费项目：1)配备容错电源转换器的多种化学能源系统，2)使用可重构电池系统的电动汽车直流快速充电，以及3)高密度液体冷却电力电子和氮化镓集成电路。CRC项目将资助多伦多大学电动汽车研究中心(UTEV)的研究生，同时促进加拿大国内外的行业和学术合作。这项研究将通过高效、低成本、高可靠性和弹性的电力电子转换器，利用宽带隙半导体的潜力，加速全球交通和工业部门的去碳化。

The transportation sector accounts for one quarter of greenhouse gas emissions in Canada. Federal mandates dictate that at least 60% of all new vehicles sold in 2030 must be zero-emission vehicles (ZEVs), before rising to 100 per cent in 2035. Given that in 2021 only about 5% of vehicles sold in Canada were EVs, major innovations both within EVs and at the infrastructure level are desperately needed. The second-term CRC research program's objectives are to address the two key hurdles to mass adoption of electric vehicles (EV): 1) the limited real-world performance of EV battery packs, which impacts EV pricing, longevity and driving range in cold climates and 2) the lack of cheap, modular and compact DC fast-charging infrastructure, which is critical to enable inter-city and rural travel. The five-year program is organized into three complimentary Thrusts: 1) multi-chemistry energy systems with fault-tolerant power converters, 2) EV DC fast charging using reconfigurable battery systems, and 3) high-density liquid-cooled power electronics and gallium nitride integrated circuits. The CRC program will fund graduate students at the University of Toronto Eclectric Vehicle Research Centre (UTEV), while promoting industry and academic partnerships in Canada and abroad. The research will accelerate the de-carbonization of global transportation and industrial sectors through efficient, low-cost, high-reliability and resilient power electronic converters, by leveraging the potential of wide-bandgap semiconductors.
