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.
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.
Power Integrations has developed the ChiPhy family of
AC-DC wall-charger interface ICs which, when combined with the company's
AC-DC switcher ICs, incorporates all of the necessary elements to add rapid charging functionality to
AC-DC wall chargers.
A Polygon-Connected Autotransformer-Based 24-pulse
AC-DC converter is reported in [18] which has THD variation of 4.48% to 5.65% from full-load to light-load (20% of full-load).
Power Integrations (NASDAQ: POWI) reported it has introduced CHY100, the first
AC-DC wall-charger interface IC that enables designers of mobile devices to implement the Quick Charge 2.0 protocol from Qualcomm (NASDAQ: QCOM).
Under this agreement Luso becomes UK and Ireland distributor for the N2Power range of ultra-small high-efficiency
AC-DC and DC-DC power supplies.
