“…It can be seen that a bidirectional power converter must also be used to control the grid current according to the energy demand. Many topologies can be chosen for this purpose, e.g., a bidirectional two-phase interleaved converter [15]. However, the voltage stress across the switches is equal to the dc-link voltage, what may lead to the use of metal oxide semiconductor field effect transistors (MOSFETs) with high voltage ratings and cost.…”

Electric vehicles (EVs) powered by batteries and other energy storage devices (ESDs), e.g., ultracapacitors, are expected to play an important role in the development of a more sustainable future. In this context, charging stations (CSs) are supposed to become the main sources of energy for charging the batteries, being strongly dependent on power electronic converters. This paper analyzes a bidirectional single-phase, three-level stacked neutral-point-clamped (3L-SNPC) converter for CS applications, which may behave as a rectifier or an inverter depending on the power flow direction. Besides, the derived analysis can be easily extended to the development of a three-phase version. Considering that the CS is capable of integrating the utility grid and renewable energy sources, it is possible to absorb or inject energy into the ac grid with high power factor and reduced harmonic content of the current. The main advantages of the bidirectional topology are the existence of a three-level voltage waveform across each leg and the neutral point, while filtering requirements are reduced when compared with typical two-level structures used in EV CSs; the voltage stresses on all semiconductors are equal to half of the total dc-link voltage; power factor is nearly unity in any operation mode; and the voltages across the dc-link capacitors are balanced. The thorough design of the power and control stages is presented, as well as experimental results from a laboratory prototype are discussed in detail.INDEX TERMS Bidirectional converters, charging stations, electric vehicles, resonant controller.

“…Super capacitors can be applied to extend the structure of high-power EVs, which make them complicated, heavy, and expensive. In Wang et al (2019a), a two-phase bidirectional interleaved converter for EVs was suggested. This converter has quick and minimal overshoot switching performance and may be used in both buck and boost mode.…”

Electric vehicle technology has recently drawn a lot of interest on a global scale due to improved performance in its efficiency and the capability to solve the problems of carbon emission. As such, electric vehicles are the key to achieving sustainable development goals. This review article analyzes deeply the previous technical developments of electric vehicles, focusing on important topics like battery management systems, technologies of power electronics, techniques of charging, and the relevant algorithms and improvements. In addition, several critical problems, and difficulties are presented in order to pinpoint the gaps in the literature. To address the analysis of battery behavior, battery condition monitoring, real-time control design, temperature control, fault diagnostics, and efficiency of battery model are considered. This study highlighted the estimation techniques that predict the internal battery conditions such as internal temperature, state of health, and state of charge, which are difficult to be directly monitored and determined. A lithium-ion battery, a super-capacitor, and related bidirectional DC/DC converters constitutes the infrastructure of a hybrid power system. This review offers useful and practical recommendations for the future development of electric vehicle technology which in turn help electric vehicle engineers to be acquainted with effective techniques of battery storage, battery charging strategies, converters, controllers, and optimization methods to satisfy the requirements of sustainable development goals. Accordingly, this review article will be a platform and future guide for those who are interesting in the field of energy management and its development.

Rangkaian konverter arus searah dibutuhkan untuk mengatur arah aliran daya yang mengalir pada baterai dengan tegangan yang lebih tinggi dan baterai dengan tegangan yang lebih rendah. Pengaturan ini diperlukan untuk menyesuaikan arah aliran daya dengan kebutuhan beban. Dalam penelitian ini telah dirancang Two Phase Interleaved Bidirectional DC-DC Converter berbasis Mikrokontroler dsPIC30F2020 yang mampu menghasilkan riak arus keluaran yang semakin halus dengan fitur phase shift. Pengujian dilakukan dengan variasi duty cycle pada rentang 35% 65% dengan interval nilai duty cycle sebesar 5% untuk mengetahui arah aliran daya pada baterai 24V sebagai tegangan sisi tinggi dan baterai 12V sebagai tegangan sisi rendah. Hasil pengujian menunjukkan bahwa saat nilai duty cycle berada diatas 50%, maka konverter akan bekerja dalam mode buck dan mengalirkan daya dari baterai 24V menuju baterai 12V. Sedangkan saat nilai duty cycle berada dibawah 50%, maka konverter akan bekerja dalam mode boost dan mengalirkan daya dari baterai 12V menuju baterai 24V. Fitur phase shift yang diatur menggunakan mikrokontroler 16 bit dsPIC30F2020 menyebabkan arus yang mengalir pada dua buah induktor tidak mengalami kenaikan maupun penurunan secara bersamaan sehingga menghasilkan riak arus keluaran sebesar 21,42% dari riak arus yang mengalir pada salah satu induktor.Kata kunci: Two Phase Interleaved Bidirectional DC-DC Converter, buck, boost, dsPIC30F2020, phase shift.
