Reasonable Rated Voltage of High and Medium Power Adjustable-Speed Drives for Energy Saving

Ma Xiaoliang

Strategic Study of CAE 2001, Volume 3, Issue 11, Pages 80-84

Abstract:

A large amount of energy will be saved if adjustable-speed drives are adopted by high and medium powerThe power range of most of the drives is within 0.2～2 MW.The rated voltage of most of the motors in the power range is 10 kV because the power supply is 10 kVmotor is fed by a 10 kV inverter, is not reasonable because this kind of inverter consists of a lot of powerThe reasonable rated voltages of motors and inverters with different power grades are investigated and

Advancement in materials for energy-saving lighting devices

Tak H. KIM, Wentai WANG, Qin LI

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1, Pages 13-26 doi: 10.1007/s11705-011-1168-y

Abstract: This review provides a comprehensive account of energy efficient lighting devices, their working principles and the advancement of these materials as an underpinning to the development of technology. Particular attention has been given to solid state lighting devices and their applications since they have attracted the most interest and are the most promising. Solid state lighting devices including white light emitting diodes (LEDs), organic LEDs (OLEDs), quantum-dot LEDs (QLEDs) and carbon-dot LEDs (CLEDs) are promising energy efficient lighting sources for displays and general lighting. However there is no universal solution that will give better performance and efficiency for all types of applications. LEDs are replacing traditional lamps for both general lighting and display applications, whereas OLEDs are finding their own special applications in various areas. QLEDs and CLEDs have advantages such as high quantum yields, narrow emission spectra, tunable emission spectra and good stability over OLEDs, so applications for these devices are being extended to new types of lighting sources. There is a great deal of research on these materials and their processing technologies and the commercial viability of these technologies appears strong.
