Upcoming Tutorials - NEW in 2019!

There will be 4 tutorials presented in this offering:

Session 1 - Smart Power Electronics Based Active Battery Energy Management Systems for Electric Transportation - Monday, February 4, 2019 2PM-3:30PM EDT

Abstract:  More recently, the trend in the auto industry is to move towards electric modes of transport as well as autonomous e-mobility (self-powered cars and urban mass mobility). Hence, it has become imperative to find a solution, to manage energy production and usage accurately, especially within the context of future electric energy storage systems. Enhancing the life of Lithium-ion (Li-ion) battery packs has been the topic of much interest in the auto industry. In this framework, the role of on-board cell voltage balancing of Li-ion batteries will be highlighted in this talk. This is a very important topic in the context of battery energy storage cost and life/state-of-charge, SOC/state-of-health, and SOH monitoring. Li-ion batteries provide a reasonable solution for e-transport; however, the main issues include: Cycle life (range anxiety), calendar life, energy density, power density, and safety. These issues can be addressed effectively by using a simple practical approach: a power electronics based dynamic cell voltage equalizer. The design and implementation of a novel, reduced-parts DC/DC converters for battery cell-voltage-equalization will be discussed. The design, implementation, and testing/validation of the active cell-balancing DC/DC converter topology will be presented.

Session 2:  Novel Power Converters for DC Fast Charging - Monday, February 11, 2PM-3:30PM EDT

Abstract: This presentation will review presently available level 3 DC fast charging systems, followed by a brief description and evaluation of DC fast-charging infrastructure. Different power converter topologies and viable configurations will be presented, compared, and evaluated. These topologies will be compared based on their power levels, efficiency, cost, and specifications. The talk will introduce for the first time the possibility of employing a 3-phase, 3-switch (TPTS) converter as a single-stage charger for DC fast charging. A new modulation technique for controlling a TPTS converter will also be introduced. Experimental verification and test results of the designed converter/charger prototype will be presented.

Session 3: Integrated PV/Smart-grid Based Charging Applications, Monday, February 25, 2PM-3:30PM EDT

Abstract:  This presentation will introduce both home and public charging interface designs from a power electronic intensive solution perspective. Several grid-connected as well as PV/grid interface topologies for EV charging will be presented, with detailed comparative points highlighted. The modeling, sizing, design, and implementation of a novel high-efficiency, single-stage PV/grid/EV charging infrastructure will be presented. The novel charging infrastructure is universal and smart in nature, whereby EV batteries of different chemistries as well as charging rates can be accommodated in a single power conversion stage. The designed charging infrastructure will support both Level 1 as well as Level 2 DC charging. This is a new concept for charging EVs. This is critical, due to the inevitable penetration of renewable energy sources, which are inherently DC in nature. According to SAE J1772 standards, DC charging of EVs can be performed at 200-450 V DC, 36.0 kW, and 80 A (DC Level 1), and up to 200 A, 90 kW (DC Level 2).

Session 4: High-Efficiency, Wireless Fast Charging Concepts and Methodologies, Monday, March 4, 2PM-3:30PM EDT

Abstract:  More recently, with the automotive market getting introduced to several EV models, the need for charging them within cities, suburbs, and highways, has driven power electronics engineers towards innovative ideas to solve the future charging infrastructure problem. Plugged charging topologies have been investigated thoroughly in recent years, based on existing SAE J1772 standards for AC and DC charging, ranging from 1.5 kW-to-50 kW-to120 kW. On the other hand, in the last 5 years or so, power supply and charger manufacturing companies have been seriously started looking at wireless charging as an attractive solution, to avoid physical drawbacks of wired or plugged versions of charging. The high-level goals of this talk is to focus on introducing advanced power electronics solutions for rapid charging using wireless power transfer. Both inductive power transfer (IPT) as well as capacitive power transfer (CPT, electrostatic) techniques of wireless charging will be introduced. The major market for IPT-based wireless charging is the mass transit industry, such as electric trains, buses, and trams, in the range of 100-250 kW, while both IPT and CPT could be used for charging small utility-grade EVs (golf carts/security vehicles), in smaller sizes of 1.0 kW.

Critical issues, such as IPT transfer coil design, CPT capacitor dielectric medium/transfer plate designs, and converter topologies, will be discussed. Detailed results of finite element analysis (FEA) designs for energizer and pick-up coils will be presented. Specific emphasis is placed on reducing the effect of skin effect and proximity effect for both in-motion and static charging (for varied switching frequencies and air-gap lengths). An important aspect that will also be covered is the design of charger topologies on the secondary side of the IPT or CPT system. The challenge is to come up with 1-stage power conversion techniques, including high-frequency (HF) AC/DC rectification and DC/DC charger functionalities, with conversion efficiencies of 98% or higher.
