Title Proper : ANALYSIS OF SOME APPLICATION ASPECTS IN MODERN (PWM) ADJUSTABLE SPEED DRIVE SYSTEMS AND NEW SOLUTIONS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : In this dissertation. the effects of application aspects such as high common modedv/dt. high differential mode dvdt. neutral shift. and capacitor heating in modem PWMadjustable speed AC motor drives are thoroughly analyzed. These aspects have beendescribed as the cause for premature failures in many modem PWM adjustable speed ACmotor drive (ASD) system installations. First, an in depth analysis of the effect of highcommon mode and high differential mode tlddt on two popular ASD systems ispresented. Then. analysis of the effect of neutral shift on two medium-voltage (4160V)ASD systems is presented. Finally. a new method to evaluate dc-link capacitor heating inASD systems is proposed. The evaluation is based on the level of ripple currents dc-linkcapacitors can endure that lead to self-heating....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
