“…Non-isolated DC-DC converters are frequently used in medium and high-power vehicular applications [99][100][101]. Among them, conventional boost DC-DC converters and interleaved Boost DC-DC converters are commonly used for BEV and PHEV powertrains due to their simple architecture, cost-effectiveness and accessible control strategy.…”

This article reviews the design and evaluation of different DC-DC converter topologies for Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs). The design and evaluation of these converter topologies are presented, analyzed and compared in terms of output power, component count, switching frequency, electromagnetic interference (EMI), losses, effectiveness, reliability and cost. This paper also evaluates the architecture, merits and demerits of converter topologies (AC-DC and DC-DC) for Fast Charging Stations (FCHARs). On the basis of this analysis, it has found that the Multidevice Interleaved DC-DC Bidirectional Converter (MDIBC) is the most suitable topology for high-power BEVs and PHEVs (> 10kW), thanks to its low input current ripples, low output voltage ripples, low electromagnetic interference, bidirectionality, high efficiency and high reliability. In contrast, for low-power electric vehicles (<10 kW), it is tough to recommend a single candidate that is the best in all possible aspects. However, the Sinusoidal Amplitude Converter, the Z-Source DC-DC converter and the boost DC-DC converter with resonant circuit are more suitable for low-power BEVs and PHEVs because of their soft switching, noise-free operation, low switching loss and high efficiency. Finally, this paper explores the opportunity of using wide band gap semiconductors (WBGSs) in DC-DC converters for BEVs, PHEVs and converters for FCHARs. Specifically, the future roadmap of research for WBGSs, modeling of emerging topologies and design techniques of the control system for BEV and PHEV powertrains are also presented in detail, which will certainly help researchers and solution engineers of automotive industries to select the suitable converter topology to achieve the growth of projected power density.

Abstract-Flyback is one of high voltage generation methods using a low voltage source. This method has a simple circuit, which consists of two main components for generating the high voltage. In this study, flyback method is used to generate high voltage on plasma electrolytic oxidation (PEO) application. PEO is a process that combine electrochemical oxidation process and high voltage spark. This application needs high voltage to produce plasma. The plasma is used to form a new surface coating on metal. Flyback circuit is succesfully simulated on LTSpice IV. Voltage value and waveform on simulation has been observed and compared with the real one. The measured and observed part is IGB gate, output voltage of transformer before diode, and load voltage after diode. Flyback effect and waveform on simulation has the similiar result with the real one. A 10 volt input voltage can produce output voltage on the average of 1 kilovolt. Therefore, flyback simulation is able to represent flyback ability on real circuit for generating high voltage which can be used on high voltage generation for PEO application.Intisari-Metode flyback merupakan salah satu metode pembangkitan tegangan tinggi dengan sumber tegangan rendah. Metode ini memiliki rangkaian yang sederhana. Rangkaian flyback hanya memiliki dua komponen utama untuk membangkitkan tegangan tinggi. Pada makalah ini, digunakan metode flyback untuk merancang pembangkitan tegangan tinggi pada aplikasi plasma electrolytic oxidation (PEO). PEO merupakan suatu proses kombinasi dari sebuah proses oksidasi elektrokimia dan penerapan percikan (spark) tegangan tinggi. Aplikasi PEO membutuhkan tegangan tinggi untuk menghasilkan plasma. Plasma pada proses tersebut digunakan untuk membentuk lapisan permukaan baru pada sebuah permukaan metal. Rangkaian flyback yang disimulasikan dengan LTSpice IV berhasil dilakukan. Nilai tegangan dan bentuk geombang pada simulasi telah diamati dan dibandingkan dengan pengujian rangkaian flyback yang dibuat. Tiga titik yang diukur dan diamati pada simulasi dan pengujian adalah tegangan pada gate IGBT, tegangan keluaran transformator sebelum diode, dan tegangan pada beban setelah diode. Efek flyback yang terjadi dan bentuk gelombang yang dihasilkan simulasi mendekati hasil pengujian. Dengan sumber tegangan pulsa 10 volt, rangkaian ini menghasilkan tegangan keluaran rata-rata 1 kilovolt. Dengan demikian, simulasi flyback mampu merepresentasikan kemampuan rangkaian flyback yang telah dibuat untuk menghasilkan tegangan tinggi, sehingga metode flyback dapat digunakan pada pembangkitan tegangan tinggi untuk aplikasi PEO.Kata Kunci-flyback, tegangan tinggi, plasma, plasma elecrolytic oxidation, PEO.I. PENDAHULUAN Pada umumnya, pembangkitan tegangan tinggi dilakukan dengan rangkaian yang berukuran besar dan rumit. Seiring berkembangnya penelitian tentang pengaplikasian tegangan tinggi di segala bidang saat ini, dibutuhkan rangkaian yang lebih sederhana untuk dapat membangkitkan tegangan tinggi. Rangkaian yang lebih sederhana dapat memudahkan penelitian di la...
