STMicroelectronics to Showcase its Latest Solutions for Power-Supply Systems ...
/PRNewswire/ -- STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the entire spectrum of electronics applications, and a world leader in integrated circuits, will demonstrate its advanced solutions for power systems at Techno-Frontier 2011.These solutions, which combine ST's latest technologies and system know-how, make possible both high-efficiency power conversion and power supplies, while also contributing to an energy-saving society, in which limited resources will be used more efficiently. Various demonstrations, development boards and products will be available at ST's booth.
Main solutions to be highlighted at the ST booth
Solar battery solutions
In solar-power applications, ST will demonstrate the SPV1020, a DC-DC converter IC embedded with an algorithm of maximum power point tracking (MPPT). The SPV1020 is an IC with both power optimization and power conversion functions, which can individually set the MPPT of the solar power cell, to maximize the power output from each cell. ST will also demonstrate the SPV1001 cool bypass switch, which integrates low loss MOSFETs and precision controllers to allow each solar battery cell to deliver more electricity, effectively equipping the SPV1001 with the same capabilities as bypass diodes. In addition, ST will introduce solutions for micro inverters, in which the output and power from each cell is optimized and maximized.
In mobile-equipment battery chargers, ST will demonstrate the SPV1040, a battery charger IC for mobile equipment that is equipped with a solar battery panel. Unlike conventional products that control power generated by multiple solar battery cells, the SPV1040 (which can boost power from one solar battery cell) is a highly significant product; it is equipped with MPPT functionality to optimize the output of solar battery panels, in order to secure the maximum amount of power generation. In hosting the demo of the SPV1040, mobile phones will be charged by using a battery charger that is equipped with a solar battery panel.
Secondary battery solutions
In portable battery-charger applications, ST will demonstrate the STBC21, which gives total control of lithium-ion battery charging, if installed in portable electrical-equipment battery chargers or in the equipment itself. The STBC21 achieves higher efficiency in battery chargers, and has excellent battery protection and precise control of charging time, indication, current, and voltage. At the booth, ST will also showcase portable charger solutions for easy use of chargers away from home. These solutions will be demonstrated by using the STBC21 demo kit in combination with a remaining battery level detection IC, a USB detection IC and a solar battery cell.

Visit : http://www.EdisonSecret.com And Get Ready To Discover Thomas Edisons Suppressed Gem Of The Energy Industry, That Will Make It Possible To Generate more than 1000 Kwh (Kilowatt-hours) Per Month From Your Household, Using This Secret Invention of Thomas Edison That The Power Companies Never Wanted You To Know About. Edisons Device For Tapping The Force Of The Earth Core From The Ground Is Finally Out On The Open. Even a person with zero technical knowledge can build this. Features that the Edisons Current offers: Fairly compact device, requires a small amount of space, can work in every home. Works in all conditions, isnt affected by climate, can work in both hot or cold conditions without any problem. It can eliminate the power bill of an average household by at least 50% when implemented on a small scale, and it can eliminate the power bill completely when implemented on a full scale. The material needed to build it is easily obtainable anywhere in the world. The process has been simplified to the bone, even if youre a novice, you will be able to do this. Contains a free bonus chapter on reducing oil dependency and energy conservation. Runs quietly and its eco-friendly, it doesnt pollute the environment. Doesnt contain any hazardous parts or components, the device is safe, even if you have little children in your household. You Only Need A Few Spare Hours, Some Very Basic Tools, And You Could Eliminate Your Power Bill FOREVER. This is the only device that successfully generates power from the ground, harnessing the electric current contained in the earth core. Thanks to an inside source that leaked the complete blueprints of the Edison Current Device, our crack team of underground scientists was able to optimize the device, so that it can be easily constructed with parts that can be found at any local hardware store.Even if youre not handy with the tools, the blueprints show you what to do in detail, thus you wont have any trouble putting this device together. This is completely free electrical energy, which can fully power your home for free.
