Analysis of Single Phase Induction motor controlling of an Electric Vehicle through a Reduced Switch Multilevel Inverters

Abstract

Multilevel inverters (MLIs) have gained an increasingly high profile in the area of power electronics because they are compact in their design and high efficiency, particularly in electric vehicles (EVs) and photovoltaic (PV) systems. This study introduces an innovative MLI architecture leveraging the switched capacitor (SC) methodology to generate higher voltage levels with fewer components. By cascading SC units, an inverter design remains streamlined, effectively reducing a need for multiple active switches and gate driver circuits. This results in the more cost-effective, compact, and reliable system. To ensure stable DC voltage from a solar input, the fuzzy logic controller (FLC) is implemented in conjunction with the Single Input Multi Output (SIMO) converter, which boosts an input voltage above a DC link level. A proposed inverter topology is evaluated against other reduced-switch MLI configurations acquired from metrics like total harmonic distortion (THD), efficiency, and component count. Simulations, conducted in MATLAB/Simulink, along with experimental testing under variable load conditions, validate a practicality and performance of a design for use in EVs and renewable energy technologies.
