Abstract
This thesis presents a comprehensive investigation on the reduction of input current stress in electric bicycle controllers through the implementation of a two-phase interleaved buck converter. Electric bicycles (e-bikes) have emerged as a sustainable and eco-friendly transportation option, and the efficiency and reliability of their power electronic converters play a crucial role in optimizing their performance. The input current stress imposed on the converter is a critical factor that impacts its efficiency, power losses, and overall system lifespan. This research aims to address this challenge by proposing a novel approach based on
a two-phase interleaved buck converter. The objectives of this study involve an in-depth analysis of the existing challenges associated with input current stress in electric bicycle controllers, followed by the development of a two phase interleaved buck converter design. The design parameters, such as switching frequency, inductor and capacitor values, and control strategy, are carefully considered to minimize input current stress while ensuring the stability and reliability of the system. A comprehensive control strategy is developed to regulate the output voltage and current of the proposed converter within specified limits.
To evaluate the performance of the designed converter, extensive simulations are conducted using MATLAB/Simulink. The efficiency, power losses, and thermal behavior of the converter are analyzed and compared with conventional single-phase buck converters commonly used in electric bicycle controllers. The results of the comparative study highlight the advantages of the proposed converter in terms of reduced input current stress and improved overall system performance.
The expected outcomes of this research include a significant reduction in input current stress, leading to enhanced efficiency and reduced power losses in electric bicycle controllers. By employing the two-phase interleaved buck converter, the system performance and reliability are expected to be improved, ultimately contributing to the advancement of power electronics technology in the electric bicycle industry. This research contributes to the body of knowledge by proposing an innovative solution for reducing input current stress in electric bicycle controllers. The findings of this study have practical implications for the design and development of more efficient and reliable power electronic converters in the field of electric transportation systems. The outcomes of this research provide valuable insights for engineers, researchers, and manufacturers involved in the design and optimization of electric bicycle controllers, with potential applications in various other electric vehicle system
