Preventing Magnetic Saturation and Reducing Torque Ripples in Induction Motors Using an Improved Field-Oriented Control System Based on Sliding Mode Technology
Field-oriented control (FOC) is a widely used strategy that allows independent control of torque and flux in induction motor systems. By applying Park transforms to convert three-phase signals into a dq reference frame, accurate motor speed regulation is achieved while maintaining constant flux for…

Buck Converter Modelling for Supercapacitors Fast Charging in CCM
Supercapacitors (SCs) can handle thousands of charge/discharge cycles with high peak currents, largely due to their low equivalent series resistance (ESR). However, this can be a drawback when high charging currents are to be regulated, since DC–DC converters must work in continuous current mode…
