A Review of High Efficiency Power Converters for Electric Vehicles Applications
P. Karthikeyan, S. Prakash
Abstract
To eliminate the need for on-board chargers and enable direct battery charging, power electronic converters are employed to convert AC supply into high-voltage Direct Current (DC). These converters are crucial for implementing advanced management techniques that regulate the charging rate and protect the battery from potential damage. This study analyses the performance of various power converters with the goal of selecting the most suitable one for Electric Vehicle (EV) applications. The primary criteria for selection include minimizing Total Harmonic Distortion (THD), maximizing power output, and achieving high efficiency. The converters include the Cuk converter, Single-Ended Primary Inductor Converter (SEPIC), Conventional Bi-directional DC-DC converters, and a DC-DC converter with a boost feature and integrated inductor. The primary research objective is to identify a power converter that supports the development of a sustainable and eco-friendly environment while meeting the performance requirements for EV applications.
