CONTROL OF RIPPLE ELIMINATORS TO IMPROVE THE POWER QUALITY OF DC SYSTEMS AND REDUCE THE USAGE OF ELECTROLYTIC CAPACITORS

Control of Ripple Eliminators to Improve the Power Quality of DC Systems and Reduce the Usage of Electrolytic Capacitors

The problem of voltage/current ripples has become a primary power quality issue for dc systems, which could seriously degrade the performance on both the source side and the load side and lead to reliability concerns.In this paper, a single-phase Pulse width modulation-controlled rectifier is taken as an example to investigate how active control st

Registration for Optical Multimodal Remote Sensing Images Based on FAST Detection, Window Selection, and Histogram Specification

In recent years, digital frame cameras have been increasingly used for remote sensing applications.However, it is always a challenge to align or register images captured with different cameras or different imaging sensor units.In this research, a novel registration method was proposed.Coarse registration was first applied to approximately align the
