“…For design and development of ultra-fast charging systems, a modular converter approach is an appropriate solution. Hence, the current topology, which is proposed for the 600 kW DC ultra-fast charger, is realised by merging four AFE converters with each other in a parallel configuration, as shown in Figure 7 [71]. A comparative analysis has been performed between silicon and silicon carbidebased semiconductors for each module at a power rating of 150 kW.…”

“…The simplest way to control the parallel converters is to use a single controller. Figure 9 demonstrates the centralised control system for modular Active Front-End rectifiers [71]. However, this mode of control can also be used for other bidirectional parallel converters employed in the V2G/G2V systems, such as DC-DC converters, single phase power factor correction rectifiers, etc.…”

Today, there are many recent developments that focus on improving the electric vehicles and their components, particularly regarding advances in batteries, energy management systems, autonomous features and charging infrastructure. This plays an important role in developing next electric vehicle generations, and encourages more efficient and sustainable eco-system. This paper not only provides insights in the latest knowledge and developments of electric vehicles (EVs), but also the new promising and novel EV technologies based on scientific facts and figures—which could be from a technological point of view feasible by 2030. In this paper, potential design and modelling tools, such as digital twin with connected Internet-of-Things (IoT), are addressed. Furthermore, the potential technological challenges and research gaps in all EV aspects from hard-core battery material sciences, power electronics and powertrain engineering up to environmental assessments and market considerations are addressed. The paper is based on the knowledge of the 140+ FTE counting multidisciplinary research centre MOBI-VUB, that has a 40-year track record in the field of electric vehicles and e-mobility.

“…Some of the important metrics to evaluate an AFE system are cost, current Total Harmonic Distortion (THD), efficiency, thermal behavior, reliability, and size [8]. Earlier studies demonstrated that splitting the power of the AFE system among several parallel modules can increase the system efficiency and expected lifetime [5], while also decreasing its grid impact [9]. However, increasing the number of modules can increase the system's cost and complexity.…”

This paper presents a design optimization for grid-connected modular Active Front-End (AFE) rectifiers with an evaluation of efficiency, lifetime, cost, volume, and weight. This tool optimizes the rectifier switching frequency, component sizing and selection, and the number of parallel converters by designing and evaluating every possible configuration of the AFE rectifier system defined by the end user. The design of the LCL filter, magnetic design of inductors, selection of the inductor core and winding, and selection of SiC switches and MLC capacitors are discussed. Rapid Low-Fidelity (Lo-Fi) electro-thermal and lifetime models that are fast enough to be used in an optimization process have been developed. The rapid Lo-Fi models estimate component losses, temperatures, and lifetime for given load profiles and converter configurations. This Lo-Fi approach accelerates the processing time to generate the thermal data for the converter mission profile and allows us to skip rainflow-counting algorithm to assess the accumulated thermal damage to the SiC switches at the design and development stage. This in turn allows engineers to design converters with a longer predicted lifetime. Moreover, optimization of the grid-side three-phase LCL filter is performed considering efficiency, cost, and volume trade-off between the grid-side and converter-side inductors to achieve up to 50% decrease in losses, and 23% decrease in cost. Moreover, a 21-22% decrease in the system losses, 23-27% decrease in system cost, and tenfold improvement of the system lifetime can be achieved by optimizing the converter switching frequency and number of parallel modules. A 15 kW hardware prototype consisting of three 5 kW AFE rectifier modules is built and used to validate the efficiency from the fast Lo-Fi models. The validation of the detailed loss model and junction temperature swing is performed against a High-Fidelity (Hi-Fi) simulation in MATLAB Simulink environment.INDEX TERMS Active front-end rectifier, modular, optimization, parallel converters, rapid electro-thermal model, lifetime model, LCL design.
