Torque Ripple Reduction for Switched Reluctance Motor with Optimized PWM Control Strategy
Energies, 2018 The high current ripple and torque ripple are the main drawbacks of the switched reluctance motor (SRM) since the nonlinearity and double saliency, which limits its applications. In order to eliminate the current variation and torque ripple, an optimized

Techniques for input ripple current cancellation: classification and implementation [PDF]
2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2000 Switching power supplies, due to their high-frequency switching operation, draw a substantial amount of input ripple current, which manifests as undesirable electromagnetic interference (EMI). This paper discusses the cancellation methods, and classifies the basic circuit configurations for ripple current cancellation.

Stator Interturn Fault Detection in Permanent-Magnet Machines Using PWM Ripple Current Measurement [PDF]
, 2014 This paper proposes a novel method of interturn fault detection based on measurement of pulsewidth modulation (PWM) ripple current. The method uses the ripple current generated by the switching inverter as a means to detect interturn fault.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
