Öz Gelecekte fosil yakıtlı araçların yerini alacağı tahmin edilen elektrikli araç teknolojisinde batarya şarjı en önemli konulardan birisidir. Doğru ve verimli bir şarj işlemi için batarya şarj modülü iyi tasarlanmalı, yaratacağı olumsuz etkiler giderilmelidir. Şarj modülünün olumsuz özelliklerinden birisi bağlı olduğu şebeke üzerinde yaptığı bozucu etkilerdir. Bu etkiler, düşük güç faktörü ve çekilen şebeke akımında oluşan yüksek harmonik distorsiyondur. Bu çalışmada şebekeden çekilen akımın harmonik içeriğinin azaltılması ve bire yakın güç faktörü elde edilmesi amacıyla 1. seviye (3 kW) on board batarya şarjı için yükseltici (boost) tip dönüştürücü içeren tek fazlı Güç Faktörü Düzeltici (PFC) devre yapısı incelendi. Dönüştürücü Matlab/Simulink ortamında simule edildi. Şebeke tarafında oluşan dalga şekillerinin, şebeke akımı harmonik yüzdesi, güç faktörü ve sistemin verim değerlerinin PFC'siz yapıya göre oldukça iyileştirilmiş olduğu görüldü.

“…Among them, the PFC converter with boost converter topology has recently gained significant attention due to its simplicity in design and control [6]. Moreover, the different configurations in the boost PFC topology are discussed in [7]. The OBCs in EVs and PHEVs have the typical two-stage layout as shown in Fig.…”

On-board battery chargers (OBCs) offer the feasibility of charging electric vehicles or plug-in hybrid electric vehicles with a standard household power supply. In this study, an OBC using two-mode topology (step-up or step-down) is presented. One of the main concern with two-mode topologies is the hard transitions of the converter operating from boost mode to buck mode or vice versa, which can deteriorate the performance of converter. This study provides smooth transitions between the modes and can have an output that could be more or less than the peak of input voltage. The detailed analysis of operating modes involved in the converter are analysed in the study. Moreover, the stress analysis on the components is also detailed in this study and the results are compared with existing two-mode converters. A simple dual-loop control structure with the proposed modulation technique eliminates the sub-harmonic oscillations and stabilizes the output voltage is also presented in the study. Experimental validation is performed for a 1.0 kW laboratory prototype and the results obtained are detailed in the study. This proposed converter topology can be applied as a single-stage OBC or as a power factor correction converter with variable DC link voltages in isolated two-stage OBC.

The optimal planning of electric vehicle (EV) charging stations (ECSs) with advanced control algorithms is very important to accelerate the development of EVs, which is a promising solution to reduce carbon emissions of conventional internal combustion engine vehicles (ICEVs). The large and fluctuant load currents of ECSs can bring negative impacts to both EV-related power converters and power distribution systems if the energy flow is not regulated properly. Recent review papers related to EVs found in open literature have mainly focused on the design of power converter-based chargers and power interfaces, analyses of power quality (PQ) issues, the development of wireless charging techniques, etc. There is currently no review paper that focuses on key technologies in various system configurations, optimal energy management and advanced control issues in practical applications. To compensate for this insufficiency and provide timely research directions, this paper reviews 143 previously published papers related to the aforementioned topics in recent literature including 17 EV-related review papers found in Institute of Electrical and Electronics Engineers (IEEE)/Institution of Engineering and Technology (IET) (IEEE/IET) Electronic Library (IEL) and ScienceDirect OnSite (SDOS) databases. In this paper, existing system configurations, related design methods, algorithms and key technologies for ECSs are systematically reviewed. Based on discussions given in the reviewed papers, the most popular ECS configuration is a hybrid system design that integrates renewable energy (RE)-based power generation (REBPG), various energy storage systems (ESSs), and utility grids. It is noteworthy that the addition of an ESS with properly designed control algorithms can simultaneously buffer the fast, fluctuant power demand during charging, smooth the intermittent power generation of REBPG, and increase the overall efficiency and operating flexibility of ECSs. In addition, verifying the significance of the flexibility and possible profits that portable ESSs provide in ECS networks is a potential research theme in ECS fields, in which the potential applications of portable ESSs in the grid-tied ECSs are numerous and could cover a full technical spectrum.
