Design and Development of Frequency Domain-Based Lead and Lag-Lead Controller-Based DC-DC CUK Converter for Electric Vehicle Applications
Main Article Content
Abstract
DC-DC high-power electronic converter plays an important role in the domain of fast charging of electric vehicles. Compared to other basic DC-DC converters, the Cuk converter offers advantages such as high-power extraction capability and low ripple DC output voltage, making it more suitable for electric vehicle applications. This paper aims to design a robust, novel controller for the cuk converter to improve its reliability and efficiency compared with existing controllers. This paper presents a complete proof-of-concept frequency-domain-based design of the Lead and Lag-Lead controllers for a DC-DC Cuk converter. The proposed control scheme is being implemented in MATLAB Simulink to verify the theoretical concepts. Lastly, a comparison has been made between the open-loop and closed-loop responses of the Cuk converter to validate the proposed controller.
