Harmonic Elimination of 25 kV AC Electric Railways Utilizing a New Hybrid Filter Structure [PDF]
AUT Journal of Electrical Engineering, 2017 Thyristor rectifiers are widely used in electric railways in order to control the speed. As a consequence of their usage in addition to substantial input lead current, an enormous amount of harmonics is injected into the grid.

Passive Loop Filter Assistance for CTSDMs [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2017 This brief presents a power reduction technique for continuous time sigma–delta modulators (CTSDMs). The approach consists of two elements. First, a passive low-pass filter is added in front of the modulator’s loop filter to reduce the high frequency components in the loop.
