Conventional internal combustion engine (ICE) based vehicles suffer from high emissions and high fuel consumption, especially during cold cranking and acceleration in frequent start-stop cycles. The integrated starter alternator (ISA) maintains the functions of the conventional starter and generator in an ICE vehicle, and provides a smooth start to the stopped engine. In this proposed project, a unique test cell will be designed and developed with our industry partner, D&V Electronics, to test and evaluate low-voltage, high-speed interior permanent magnet synchronous machines (IPMSM) for belt driven ISA applications. Considering the available voltage with the use of low-voltage batteries and the conversion ratio of the belt between the engine and ISA, the IPMSM under test will operate with a terminal voltage of up to 60V and generate within an extended speed range of up to 20,000 rpm. The test cell will incorporate all the hardware and software required to provide for the interconnection, operation, and evaluation of the machine being tested. Special attention will be given to investigating the technical issues and developing the proper controller for stable operation of IPMSM in torque control mode during cranking and flux weakening mode at high speeds under low terminal voltage. Moreover, the inverter, which will operate in high current conditions due to the low terminal voltage constraint, will be designed with proper thermal management and packaging to achieve high power density. Different aspects of the design and implementation of the challenging low-voltage, high-speed IPMSM drive will be covered in this proposed project. Therefore, significant knowledge and hands-on experience will be created both for our university research group and our industry partner. The expertise developed by the trained HQP will be significantly valuable to the industry for not only developing ISA for electrified powertrain applications, but also for developing the next generation of electrified vehicle architectures, such as hybrid electric and battery electric vehicles.

传统的内燃机汽车存在着高排放、高油耗的问题，尤其是在频繁启停循环的冷起动和加速过程中。集成起动机交流发电机(ISA)在内燃机汽车上保持了传统起动机和发电机的功能，并为停止的发动机提供平稳启动。在这个拟议的项目中，我们将与我们的行业合作伙伴D&V Electronics一起设计和开发一个独特的测试单元，以测试和评估用于皮带驱动ISA应用的低电压、高速内部永磁同步电机(IPMSM)。考虑到使用低压电池时的可用电压以及发动机和ISA之间皮带的转换比，测试中的IPMSM将在高达60V的终端电压下运行，并在高达20,000 rpm的扩展转速范围内发电。 测试单元将包含为被测试机器的互连、操作和评估提供所需的所有硬件和软件。重点研究IPMSM的技术问题，并开发合适的控制器，使IPMSM在起动时的转矩控制模式和在低端电压下的高速弱磁模式下稳定运行。此外，由于终端电压低的限制，逆变器将在高电流条件下运行，其设计将采用适当的热管理和封装，以实现高功率密度。 这个拟议的项目将涵盖具有挑战性的低电压、高速IPMSM驱动器的设计和实施的不同方面。因此，将为我们的大学研究小组和我们的行业合作伙伴创造重要的知识和实践经验。训练有素的HQP开发的专业知识将对行业具有重大价值，不仅可以为电动动力总成应用开发ISA，而且还可以开发下一代电动汽车架构，如混合动力和电池电动汽车。
