Analysis of Canonical Switching Inverse Buck-Boost Converter Based Electric Vehicle Drive System

The paper presents the design, analysis and control of a Canonical Switching Inverse Buck-Boost Converter (CSwI-BBC) based electric vehicle drive system. The presented CSwI-BBC converter topology is capable of performing buck and boost both operation upon the input voltage and thereby offers a wide operation range for the speed control of brushless DC motor (BLDCM) drive using DC link control algorithm. The presented system in closed- loop is capable to controlling the speed of drive by adjusting the reference DC link voltage. The scheme is mathematically modeled in this paper and Exhaustive performance analysis of CSwI-BBC based electrical vehicle drive system has been presented through the simulation results acquired in MATLAB environment. The developed Simulink model is subjected to different operating conditions and performance of the system is found quite satisfactory under steady-state and dynamic test conditions.
