Dr. Uday Deshpande, D&V Electronics, USA

Abstract:  In this webinar, the presenter will his experience and thoughts on the use of electric motor emulators for testing and validation of inverters.

The first part of the presentation will cover an overview of typical test and validation elements and steps and some of the trends considering increasing electrification and growth of electric vehicles. The second part of the presentation will discuss the essential elements of an electric motor emulator, how it can be used for testing an inverter in lieu of a conventional dyno, typical tests that can be done using an emulator test system including performance, durability, environmental, that address functionality and compliance. The third part of the presentation will cover challenges and considerations that need to kept in mind as people consider using emulator-based test systems. We will look at motor models and real-time implementation, considerations to ensure high fidelity representation of motor behavior, means and mechanisms to study faulted behaviors. Through this webinar, the audiences can expect an in-depth overview of this fast-growing approach to improve test efficiency and effectiveness and spark ideas and discussions to continuously improve design and development cycles.

Abstract: Entering the 21st century, new technologies and theories are entering the paradigm of power electronics, leading to increasing diversity of the field. As the research volume of power converter increasing fast, resemble circuits and similar operation methods are emerging in recent decades, and needed to be reorganized and studied systematically. Therefore, it could be beneficial to establish the fundamental relationships among various power converters topologies, and to link different converters with universal principles. The electrical duality has been well acknowledged when dealing with such circuit-level unifications. Meanwhile, the graphical isomorphism also shows some great potential for topology derivations and modulation innovations. Furthermore, by synergistically implementation of these two theories, the topology transformation rules can be implemented for power converters. With such relationships, the derived topology or modulations can be generalized for other topologies, therefore, further reduce the design burden and accelerate the research process. In this webinar, the basic concepts of graph theory will be introduced, followed by the discussion and demonstrations of electrical dual principles and emerging isomorphic theory for various power converters, in particular, the voltage-source converters and current-source converters. The unique cycling phenomenon of topology transformation will also be investigated. Finally, the webinar ends with discussions and further research trends in this area.

Exploring Power Conversion Based on Piezoelectrics: Converters, Components, and Capabilities

This webinar is being jointly sponsored by the IEEE Power Electronics Society Young Professionals

Jessica Boles HeadshotPresenter: Jessica Boles, Massachusetts Institute of Technology, USA

Abstract: Power electronics are integral to the advancement of transportation, renewable energy, manufacturing, healthcare, information technology, and many other major industries. These technologies increasingly demand power electronics with smaller volume, lighter weight, and lower cost, but such strides are commonly impeded by energy storage components, particularly magnetics. While magnetic components have been central to power electronics since the field's inception, their inherent challenges at small scales motivate investigation of alternative energy storage mechanisms for future miniaturized power conversion. Piezoelectrics, which store energy in the mechanical compliance and inertia of a piezoelectric material, are one such prospect; piezoelectrics show immense promise for high power density and efficiency at small scales.

In this talk, we explore how we can leverage piezoelectrics to enable substantial miniaturization of power electronics. We first identify practical dc-dc converter implementations that most efficiently utilize piezoelectrics as sole energy storage components, without magnetics. Then, we turn to the piezoelectric components themselves and evaluate piezoelectric materials, vibration modes, and geometries based on efficiency and power density capabilities. We further discuss how these capabilities scale to small sizes and how piezoelectric-based converters may pave the way for major advances in converter miniaturization.
