Presenter: Fang Luo, Stoney Brook University, USA

Abstract: In this webinar, the presenter will share his experience and questions in high-density motor drive development for All-Electric Aircraft systems from an academic point-of-view. The first part of the presentation will briefly cover converter development efforts in both non-cryogenic and cryogenic power system configurations. It will provide an architectural comparison for motor drives in such systems. The second part of the presentation will use examples from the presenter’s development to elaborate on co-design/co-optimization efforts to achieve high power-density and efficiency for the propulsion motor drives. These efforts include converter-level and component-level optimization/advancement, as well as power module packaging. The last part of the presentation will briefly introduce the modeling, testing, and analysis of the “side-effects” for the power electronics in electric aircraft propulsion systems, including partial discharge, EMI/EMC, and reflected wave influences, in such a compact, high-power application environment. Through this webinar, the audiences can expect a comprehensive overview of this emerging application and spark more innovative ideas to advance the state-of-the-art for modern power electronics.

Yue Cao Jana DoppaPresenters: Yue Cao, Oregon State University & Jana Doppa, Washington State University, USA

Abstract: This talk presents an automated design and optimization framework enabled by machine learning (ML) for electric transportation power systems. As these systems become increasingly complex and involve the co-design of multiple inter-dependent subsystems and components, a large amount of engineering time and effort is required to explore all possible designs due to large design spaces. Multi-physical domain models and simulations, essential to measure a given design’s performance, are typically computationally expensive to run – sometimes taking hours to days, depending on the system complexity. Providing an approach to drastically simplify this process – as in time and cost reduction – will allow faster and cheaper research and development throughout the transportation sector. Synergistic integration of advances in machine learning with physical domain knowledge paves one feasible pathway to practically realize this vision. Bayesian optimization (BO) is an effective machine learning framework to solve design automation problems with expensive experiments. This paper proposes a novel BO algorithm referred to as Max-value Entropy Search for Multi-objective Optimization with Constraints (MESMOC) to solve multi-objective optimization (MOO) problems with black-box constraints that can only be evaluated through design simulations. The key idea is to build statistical models of both design objectives and constraints, and use them to intelligently select the sequence of designs for evaluation based on the principle of output space entropy search – maximize the information gain about the optimal Pareto front – to efficiently uncover (approximate) Pareto optimal designs. MESMOC is capable of drastically reducing the number of design simulations to discover a high-quality Pareto front. A heavy-duty vertical-takeoff-landing (VTOL) unmanned aerial vehicle (UAV) power system is selected to demonstrate the effectiveness of the ML-based MESMOC algorithm. In several experimental trials, the ML algorithm uncovered the entire optimal Pareto front while only exploring ~4% of the design space. The proposed ML algorithm, when compared to a popular genetic algorithm, showcases superior performance.

Xibo YuanPresenter: Xibo Yuan, University of Bristol, United Kingdom

Abstract: The fast-switching speed, higher voltage and higher temperature capabilities of SiC power devices have brought in clear opportunities in achieving high-density, higher-efficiency, higher-frequency and highly-integrated motor drives. This webinar will first provide an overview of the performance of state-of-the-art SiC devices and converters and their applications in motor drive area. Then, the issues due to high frequency switching and their impact on electric machines will be explained. For example, high dv/dt and high switching frequency can cause increased level of motor over-voltage, insulation and bearing degradation and electro-magnetic interference. Under the high dv/dt of SiC drives, motor terminals will see clear over-voltage with much shorter cables than that under Si IGBT motor drives and the voltage stress will mostly drop on the first several turns of the motor windings. How the switching speed and switching frequency will affect the winding insulation (e.g. partial discharge) and motor bearing current will be explained. Experimental test results with SiC motor drives will be given and the theory behind the experimental observations will be provided.  Several potential solutions in addressing the above negative side-effects of high-frequency SiC drives will be discussed, including filters, waveform shaping through soft-switching and gate drive, alterative converter topologies, quasi-multilevel modulation, etc.  A couple of SiC motor drive examples and research projects in this area will also be presented to further demonstrate the opportunities, challenges and potential solutions mentioned above.
