A Comprehensive Review Of Dc-Dc Converters For Ev Applications, Shayan Hosseinzad, Amin Mirzaei
A Comprehensive Review Of Dc-Dc Converters For Ev Applications, Shayan Hosseinzad, Amin Mirzaei
Emirates Journal for Engineering Research
DC-DC converters in Electric vehicles (EVs) have the role of interfacing power sources to the DC-link and the DC-link to the required voltage levels for usage of different systems in EVs like DC drive, electric traction, entertainment, safety and etc. Improvement of gain and performance in these converters has a huge impact on the overall performance and future of EVs. So, different configurations have been suggested by many researches. In this paper, bidirectional DC-DC converters (BDCs) are divided into four categories as isolated-soft, isolated-hard, non-isolated-soft and non-isolated-hard depending on the isolation and type of switching. Moreover, the control strategies, comparative …

Analysis And Design Of A Fully Soft Switched Two-Level Dc-Dc Boost Converter For Electric Vehicle Applications, Amin Mirzaei, Mahdi Rezvanyvardom, Ehsan Najafi
Emirates Journal for Engineering Research
In this paper, a fully soft switched two-level DC-DC Boost converter is proposed. The converter is used only one auxiliary cell to create the soft switching conditions for all semiconductor devices. The auxiliary cell contains one auxiliary switch, one resonant capacitor, one resonant inductor and one auxiliary diode. The auxiliary switch creates the soft switching conditions by control of resonant elements. Besides, the auxiliary cell is not located in the main power path and cannot decrease the converter efficiency. It has simple operation modes. Besides, the proposed soft-switched converter is highly efficient while the control circuit is simple and remains …
Analysis And Design Of A Soft Switching Z-Source Boost Dc-Dc Converter, Mahdi Rezvanyvardom, Amin Mirzaei
Analysis And Design Of A Soft Switching Z-Source Boost Dc-Dc Converter, Mahdi Rezvanyvardom, Amin Mirzaei
Emirates Journal for Engineering Research
This paper proposes a high step-up fully soft switched Z-source Boost DC-DC converter, which uses two resonant paths to create soft switching conditions for switches and diodes and also increases the voltage gain. The proposed converter only has one switch, so it has a simple structure. Furthermore, its control circuit remains pulse width modulation. Since soft switching conditions are provided for all switching elements, the converter efficiency is very high. This converter also has all advantages of Z-source converters. The converter is analyzed and simulated in PSPICE software. The results confirm the aforementioned advantages and features of the proposed converter
