Power Electronic Autotransformer Based 3×25 kV Network for Power Quality Enhancement In Railway Supply Systems (2023)
Journal Article

State of the art single-phase AC traction systems are based on a split-phase 2×25kV supply network with multiple regularly spaced auto-transformers. The main drawbacks of this arrangement are the unbalanced currents in the three-phase grid and reacti...

Reduced sensor based single stage charger with four quadrant capabilities using predictive control (2023)
Journal Article

Single stage battery chargers eliminate the DC link capacitor stage between two stage power conversion. In this work, a reduced sensor based four quadrant charger with single stage power conversion is realized with AC–DC matrix converter topology. A...

Single-Phase Mains Fed Three-Phase Induction Motor Drive Using Improved Power Quality Direct AC–AC Converter (2023)
Journal Article

This article presents an alternative ac–ac converter topology and its control for low-speed three-phase induction motor drives fed from single-phase ac mains. The proposed matrix converter based drive system eliminates the dc link capacitor, thus fac...

Adaptive Hysteresis Current Control For Improved EMI Performance in Fast Switching Motor Drives (2023)
Conference Proceeding

Electromagnetic interference (EMI) in pulse width modulated converters is exacerbated through carrier based modulation techniques that are associated with sharp spectral peaks around multiples of the switching frequency. As a mitigation measure, spre... Read More about Adaptive Hysteresis Current Control For Improved EMI Performance in Fast Switching Motor Drives.
