Comparative analysis of modulation strategies for traction inverters in off-road agricultural electric vehicles

The advancement of electric mobility has increased the demand for efficient power electronic converters. This thesis explores different modulation strategies for traction inverters, focusing on their application in off-road agricultural electric vehicles. Various carrier-based and non-carrier-based modulation techniques are analysed for their impact on power output, efficiency, total harmonic distortion (THD), high-frequency ripple, switching losses, and dead time effects. Through simulations and comparative analysis, the optimal modulation strategy is identified to enhance inverter performance and vehicle efficiency. The findings contribute to the development of more reliable and efficient traction inverters for electric mobility applications, particularly in challenging environments such as agriculture, where efficiency and durability are critical factors.
