Harmonic mitigation through sliding DFT based single phase active power filter

Chandrasekaran, S.; Ragavan, K. (2011-12)
Phase locked loop technique based on sliding DFT for single phase grid converter applications

Chandrasekaran, S.; Ragavan, K. (Institute of Electrical and Electronics Engineers (IEEE), 2012-12-16)

The single-phase grid-connected converter is a key element in the integration of renewable energy sources to the grid. Accurate and instant estimation of grid voltage attributes like amplitude, phase angle and frequency ...
Sliding DFT assisted instantaneous symmetrical components method for estimating reference current to active power filter

Chandrasekaran, S.; Ragavan, K. (Institute of Electrical and Electronics Engineers (IEEE), 2012-08-05)

The performance of Active Power Filter (APF) is decided by the reference current estimation technique. This estimation is not straightforward in practice due to the distorted and unbalanced supply; non-linear and unbalanced ...
