“…In this study, asynchronous buck converter (ABC), synchronous buck converter (SBC), and interleaved synchronous buck converter (ISBC) topologies were examined. The total circuit efficiency decreases when high powers are reached in the conventional asynchronous buck converter circuit [13]. In dc/dc buck converter circuit topologies, ISBC topology transfers power at high efficiency [14].The following headings explain the ABC, SBC, and ISBC topologies.…”

The studies on Wireless Power Transfer (WPT) technology and peripherals in Electric Vehicle (EV) applications are intensifying. While the energy received from the WPT system is transferred to the EV battery, the direct current (dc)/dc converter circuits are used. The dc/dc buck converter topologies are one of them. The converter circuits must be highly efficient, lightweight, and compact to have a high range in EV vehicles. There are asynchronous buck, synchronous buck, and interleaved synchronous buck converter circuit topologies from the literature. In this study, the efficiency results of these circuit topologies were analyzed using MATLAB/Simulink and experimental studies. This study contributes to the literature by conducting circuit-level efficiency analysis and component-level power loss analysis. It has been observed that the interleaved synchronous buck converter circuit operates at 99% efficiency at 1066 W. In addition, it has been shared with the oscilloscope results that the current ripples of this circuit topology are lower than other circuit converters. Specifically, there has been a significant reduction of 56% in power losses, particularly in the interleaved synchronous buck converter (ISBC). This study analyzes the dynamic behavior of the dc/dc buck converter topologies, and results about their performance are given.

Electric vehicles (EVs) are getting more popular in the field of automobiles due to environmental factors and others. Since electric vehicles manage their power from the rechargeable battery so it's essential to have a reliable, efficient, and economical battery charger that can provide stable required output for the specified EV's battery. In this paper, a DC-DC converter with a modified PI controller has been presented which helps to achieve the required output voltage and high current density with negligible overshoot for the specified lithium-ion battery system to minimize the charging time. Apart from minimizing the power loss of the active switches, the proposed system minimizes the junction temperature which eventually improves the life cycle of the converter. The analysis of the proposed converter is performed both in ideal and non-ideal conditions. The power loss of the active switches and the junction temperature have also been analyzed. An economical and effective dc and ac side inductor has been designed and perform the total power loss and the temperature rise. The analysis results show that the proposed converter can maintain a power factor of more than 90% and a total harmonic distortion of less than 0.46%, which is ideal for the high-density load current. The reliability of the dc-dc converter is also evaluated. A hardware prototype has also been implemented to confirm its viability for EV battery charging applications.INDEX TERMS Buck, Lithium-ion battery charger, Electric vehicle battery charger, AC-DC converter, Isolated ac-dc converter, Power factor correction, MOSFET power loss estimation, MOSFET thermal analysis, Modified PI controller, State-space representation of converter.
