A collaborative study involving a researcher Babaei from Near East University introduces a novel unidirectional boost converter topology designed specifically for electric vehicles (EVs). With the increasing urgency to address environmental challenges such as air pollution and global warming, the development of EVs has become a priority for governments worldwide. The proposed topology offers several advantages, including the use of a single switch, ground switching, low input current ripple, and a wide range of voltage gain (VG). Additionally, it boasts high efficiency and requires fewer semiconductor and passive elements compared to existing topologies.
The study focuses on analyzing the topology’s operation in continuous current mode (CCM) and evaluating its efficiency and performance compared to previous models. Through theoretical analysis and experimental validation, the researchers demonstrate the topology’s efficacy in achieving efficient power conversion. Laboratory prototype tests confirm an impressive efficiency of 93.2%, showcasing the practical viability of the proposed design.
Key features of the topology include its ability to stabilize the dc-link or battery power supply in EVs while minimizing stress on semiconductor components. Moreover, it eliminates the need for high-frequency transformers or coupled inductors, reducing complexity and cost in implementation. The topology’s versatility extends its applicability beyond EVs, making it suitable for various dc voltage stabilization and power supply applications.
The study presents a significant advancement in power electronics for EVs, offering a streamlined and efficient solution for dc-dc conversion. By addressing key challenges such as input current ripple and semiconductor stress, the proposed topology demonstrates promise for widespread adoption in the automotive industry and beyond. The collaborative effort highlights the importance of interdisciplinary research in driving innovation and addressing pressing environmental concerns.
