Technical Solutions.IntroductionEnergy Saving TrustIn general appliances such as TVs and CD players use more electricity in standby mode than in active mode. A TV's standby generally uses 3-7W compared with around 14W when switched on, but over the course of the year this can really add up. Most modern appliances do not need a warm up time; the exception to this is ‘complex’ digital set-top devices which need to be left in standby to keep their settings. Nearly all other appliances can be turned off fully with no problems.Propose to reduce Standby Losses to 1 W•By The Lawrence Berkeley National Laboratory of the US Department of Energy. Improving the efficiency of the low-voltage transformer. Move the power switch to the high-voltage sideEnergize only the components needed for the standby services.Install “smart” recharge circuit in rechargeable appliances.Decreasing the standby power consumption www.un.org/esa/sustdev/sdissues/energy/op/clasp_mohanty.pdf•Existing theories:•Using an alternative power supply for maintaining the standby function (Expensive, environmental issues)• Photovoltaic cell or Battery to power the standby model • Employing few and smaller components and integrated circuit on power supplies.•Increase the efficiency of components that are essential for the standby function.•Self-exciting blocking oscillator system => Automatic reduction of switching frequency.•Discharging of circuit during negative half cycle => It works as the appliance were disconnected from the AC line. •Networked:Standby: The Next Generation Hans-Paul Siderius•Classification of products according to its behaviour : – On/Off products: should user plug/unplug?– Off-mode performing no function but consume power by dissipating energy by heating (stereos, printers, chargers)– Off-mode power consumption should be (near) 0 W– Standby products: Offers functionality for the user– Standby performs functions (remote c, clock, fax, copiers)– So Off-mode or Unplug is no a real solution. – Networked product: Don’t switch to standby without notification (computers connected to a network)– Goal: minimize total energy consumption– Introduction of standby modes + power managementTechnological SolutionsZERO Charger by AT&T (May 2010)www. itechnews.net/2010/03/24/att-zero-charger/#more-36013www.wireless.att.com/cell-phone-service/cell-phone-sales/promotion/zero.jsp•No waste power when left plugged in–Sensing when a cell phone is not plugged up to the charger and cutting the power supply from the socket• USB compatibility makes the AT&T ZERO Charger a convenient charging station for many mobile devices.•Author said “the draw from the new AT&T cell phone charger is so minimal”: 0.01-0.05kwh per day” •Improves charging efficiency when powering a device.SavasocketDec 2008 - April 2010www.savasocket.com Select TV Standby button on your remote controlTo protect cell phones and laptops.Power is cut when I < 66%By monitoring every 60 S“Unplug” after 3 hours.4 plugs remotely controlled2 plugs permanently onWorks with any remoteIdeal for TV, DVD, Video Rec0.19 watts in standby modeSurge Protection.Standby PlugJune 2009 www.standbyplug.com • Shut power off as soon detect standby mode. Good for Computers• Appliances will consume zero Watts. So, it will lose standby functions. The device will consume 0.4Watts.• The device must be reset to turn the appliance on. So it doesn’t detect activity on the appliance automatically.IntelliPlugs - 2009www.oneclickpower.comGood for Computers, Audio, TV’s System IntelliPlugs automatically detects low/high powerShut down/re-activate all peripherals connected to the panel when detects activity in master plugIt doesn’t work on peripherals with soft switches.Surge ProtectionIt is a 8 plugs power strip and a “Personal Sensor”It uses motion detector to manage energy use.Devices are turn on/off based on occupancy or useTime delay adjustments: from 30 Sec. to 30 Min.Surge Suppressor0.2 watts in standby modeIdeal for offices, schools, and homeWake-ON-LAN (WOL):Products with this kind of networks allow computer to be powered on or awakened form standby, hibernate or shutdown from another device on a network.STB (Set Top Box) This device interfaces with existing and developing TV’s and display systems and allows the rapid modification of functionality specifications by the user (controlling TV, VCR, Audio System, Internet, Telephone) or the service provider (software updates and security reasons).We see that standby consumption is not a simple issue for many products. The “off” mode will become obsolete in televisions and audio equipment It will become even more complex in the near future where more devices and appliances will evolve into networked products. Like for example :Fridges with a screen and internet connection.Central Air Conditioners that call the service centre if maintenance is needed.In the near future network connections will need to be powered even if they are not used.If power management is introduced for networked products, total power consumption in both active and standby modes could decrease.Thank
