This paper presents the design and analysis of a double zigzag-connected autotransformer based 24-phase
ac-dc converter which supplies direct torque controlled induction motor drives (DTCIMD's) in order to have better power quality conditions at the point of common coupling.
DOUBLE ZIGZAG-CONNECTED AUTOTRANSFORMER-BASED 24-PULSE AC-DC CONVERTER FOR POWER QUALITY IMPROVEMENT
Corona, CA, October 13, 2014 --(PR.com)-- Makers of external
ac-dc power adapters will discover that emerging wireless power technologies are at the same time a longer-term threat to sales growth and a short-term opportunity: That is one of the key findings of Darnell Group's Eleventh Edition report presented by Marketinforesearch.com on “External
AC-DC Power Supplies: Worldwide Forecasts.” The elimination of the need to maintain multiple external power supplies, one for each electronic device, has long been a goal for both the consumers and manufacturers of consumer electronics equipment and over the past several months there have been a number of developments moving the industry towards this goal.
