Optimized Modular Design of Neutral-Point-Clamped Traction Inverters for Multiple Electric Vehicles
Traction inverters play a crucial role in the growing industry of electric vehicles. On the one hand, the traction inverter design is quite challenging and needs to pursue key design goals including high efficiency, high reliability, high power density, and low weight and cost. On the other hand, a modular and scalable design methodology to cover a wide range of vehicles is highly desirable. This article explores the optimal or near-optimal design configuration of the multilevel neutral-point-clamped legs of traction inverters for three use cases: an electric motorcycle, an electric passenger car, and an electric truck. The design is based on the use of an array of switching cells. The optimal configuration and operation of the switching cells are obtained through a weighted objective function in terms of efficiency, reliability, and simplicity. The design optimization results illustrate the modularity, scalability, and suitability of the used design approach, where a single module fits all applications, and the available degrees of freedom enable the adaptation of the design to the application and operating conditions, to maximize its efficiency and reliability.

Pareto Optimised High-Frequency Planar Transformers for Electric Vehicle Chargers
The design of high-frequency transformers plays a pivotal role in electric vehicle charging systems, acting as the core component in isolated DC-DC converters. Achieving a transformer that not only operates well within the converter but also achieves high efficiency and compact size involves the balancing of numerous trade-offs. Managing the magnetic losses is essential as they dictate the efficiency but also govern the required transformer size for effective heat dissipation. This paper presents a novel transformer design method based on an exhaustive search algorithm that identifies the Pareto optimal transformers with minimised loss and weight. By introducing a Steinmetz equation filter, rapid computational speed and accuracy are combined. Loss estimations are based on experimentally validated analytical models, and the proposed methodology is experimentally validated by multiple transformer prototypes. Their operation in a dual active bridge is demonstrated by experimental measurements and circuit simulation. The results prove the effectiveness of the proposed design approach in achieving efficient and compact transformers.

Predictive Anti-Jerk and Traction Control for V2X Connected Electric Vehicles With Central Motor and Open Differential
V2X connectivity and powertrain electrification are emerging trends in the automotive sector, which enable the implementation of new control solutions. Most of the production electric vehicles have centralized powertrain architectures consisting of a single central on-board motor, a single-speed transmission, an open differential, half-shafts, and constant velocity joints. The torsional drivetrain dynamics and wheel dynamics are influenced by the open differential, especially in split-μμ scenarios, i.e., with different tire-road friction coefficients on the two wheels of the same axle, and are attenuated by the so-called anti-jerk controllers. Although a rather extensive literature discusses traction control formulations for individual wheel slip control, there is a knowledge gap on: a) model based traction controllers for centralized powertrains; and b) traction controllers using the preview of the expected tire-road friction condition ahead, e.g., obtained through V2X, for enhancing the wheel slip tracking performance. This study presents nonlinear model predictive control formulations for traction control and anti-jerk control in electric powertrains with central motor and open differential, and benefitting from the preview of the tire-road friction level. The simulation results in straight line and cornering conditions, obtained with an experimentally validated vehicle model, as well as the proof-of-concept experiments on an electric quadricycle prototype, highlight the benefits of the novel controllers.
