******This proposal involves the development of a High Power High Frequency Emulation (HPHFE) test system for key components of electrified powertrains including battery packs, electric motors, and their control systems. The HPHFE would be the first of its kind because of its flexibility to shape and emulate signals in a synchronized form with high bandwidth and high power.******The transportation sector is going through a disruptive change. Internal combustion engines are being replaced or complemented by electric propulsion systems. Powertrains are evolving rapidly and there is a pressing need for infrastructure that would support research and development of electric powertrain components, namely electric motors, battery packs, and their control systems. Accurate and complete evaluation of electric motors and batteries is essential for the automotive industry and enables them to validate and improve computer models, perform competitive benchmarking, understand how these subsystems will interact with others in the vehicle (vehicle integration), and evaluate their performance under real world conditions, including faults. ******McMaster's Centre for Mechatronics and Hybrid Technologies (CMHT) has assembled state-of-the-art equipment for electrification research that include battery cell testing as well as electric motor dynamometer testing, and associated control instrumentation. The proposed High Power High Frequency Emulation (HPHFE) test system will be able to emulate 3 synchronized high-power signals with complete flexibility in terms of their current and voltage amplitudes with a high bandwidth. The HPHFE augments and completes CMHT's capabilities and has a functionality that is unique and does not exist in any other equipment. With this emulator, the CMHT centre will be able to provide a comprehensive environment for testing of any electric motor or battery pack within the common power and torque band of most electric passenger cars (from mild hybrids to full electric vehicles). It will allow development and testing to be conducted without the constraints of their control systems and the restrictions normally associated with controller hardware (speed, wave form, electrical switching, noise). As the emulator will have full control of the voltages and currents supplied to the motor or battery under test, it will provide advanced testing capabilities and power analysis in the high power/high frequency range of operation without requiring additional instrumentation with high fidelity. The HPHFE system's new capabilities for development and testing of electrified powertrain components is transformative for the strategically important automotive sector. **

******该提案涉及开发一个高功率高频仿真（HPHFE）测试系统，用于电气化动力总成的关键部件，包括电池组，电动机及其控制系统。HPHFE将是同类产品中的第一个，因为它具有高带宽和高功率的同步形式的灵活形状和模拟信号。******交通运输业正在经历一场颠覆性的变革。内燃机正在被电力推进系统所取代或补充。动力系统正在迅速发展，迫切需要基础设施来支持电动动力系统组件的研究和开发，即电动机、电池组及其控制系统。对电动机和电池进行准确和完整的评估对于汽车行业至关重要，使他们能够验证和改进计算机模型，执行竞争性基准测试，了解这些子系统如何与车辆中的其他子系统相互作用（车辆集成），并评估其在现实世界条件下的性能，包括故障。******麦克马斯特大学机电一体化和混合动力技术中心（CMHT）为电气化研究组装了最先进的设备，包括电池测试、电动机测功仪测试和相关的控制仪器。所提出的高功率高频仿真（HPHFE）测试系统将能够模拟3个同步的高功率信号，在高带宽的电流和电压幅值方面具有完全的灵活性。HPHFE增强并完善了CMHT的能力，具有其他设备所不具备的独特功能。有了这个模拟器，CMHT中心将能够为大多数电动乘用车（从轻度混合动力汽车到全电动汽车）的通用功率和扭矩范围内的任何电动机或电池组提供全面的测试环境。它将允许开发和测试在不受控制系统限制和通常与控制器硬件相关的限制（速度，波形，电气开关，噪声）的情况下进行。由于模拟器将完全控制提供给被测电机或电池的电压和电流，因此它将在高功率/高频率范围内提供先进的测试能力和功率分析，而无需额外的高保真仪器。HPHFE系统在开发和测试电气化动力总成部件方面的新能力对于具有重要战略意义的汽车行业具有变革性意义。**
