The Impact of an Overlaid Ripple Current on Battery Aging: The Development of the SiCWell Dataset
Fast-switching semiconductors induce ripple currents on the high-voltage DC bus in the electric vehicle (EV). This paper describes the methods used in the project SiCWell and a new approach to investigate the influence of these overlaid ripples on the ...

Classifications of high resolution multitemporal remote sensing data for land use/cover mapping [PDF]
Analysis of the peak-to-peak output current ripple amplitude for multiphase and multilevel inverters is presented in this PhD thesis. The current ripple is calculated on the basis of the alternating voltage component, and peak-to-peak value is defined by

Torque Ripple Minimization Control Strategy in Synchronous Reluctance Machines
Torque smoothness is an essential requirement for high-performance motor drive applications. Synchronous reluctance machines (SyRM) have high torque ripple due to non-linear magnetic circuit and saturation.

Frequency-Controlled Current-Fed Resonant Converter with No Input Ripple Current
This paper studies a frequency-controlled current-fed resonant circuit. The adopted direct current (DC)-to-DC converter contains two boost circuits and a resonant circuit on the primary side. First, two boost circuits are connected in parallel to achieve

SEDIMENT TRANSPORT AND RIPPLES DUB TO WAVES AND CURRENTS
Water velocities and shear stresses have been determined for a laminar boundary layer of a progressive wave travelling over a regular series of ripples. The Lavrentiev variational method was used to transform conformally the water area with ripples into a strip with flat bottom, while the Lin approach permitted solution of the boundary layer equation ...

Ripple Vector Cancellation Modulation Strategy for Single-Phase Quasi-Z-Source Inverter
The double-frequency (2ω) power flows through the DC side of the single-phase quasi-Z-source inverter (QZSI) leads to the 2ω voltage ripple of capacitors and 2ω current ripple of inductors.
