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 strategies can improve the power quali... https://www.roneverhart.com/Martin-000-15SM-15-Series-12-Fret-Acoustic-Guitar-p19001/
