National Semiconductor to Introduce New Power Management Products at APEC (Applied Power Electronics Conference and Expo)

SANTA CLARA, Calif., Feb. 28 /PRNewswire-FirstCall/ -- National Semiconductor Corporation (NYSE:NSM) will showcase its newest power management technology at the Applied Power Electronics Conference and Expo (APEC) in Austin, Texas, March 6-10. National will introduce new pulse-width modulation (PWM) controllers and a high-voltage buck regulator, and provide product demonstrations in its booth (number 606/608).
In addition to demonstrating these new products, National will also exhibit its WEBENCH(R) online design tool for power management applications, as well as a tear-down of a popular consumer product that utilizes National's power management solutions. Three of National's technical experts will speak on a range of power management topics during the conference.

Green Generators National's Featured Speakers at APEC:

Thermal solar power can directly heat water in rooftop panels for houshold supplies and sunlight can also be converted to electricity using photovoltaic cells, which use semiconductors to turn photons into electricity. Both types of power need good light, .Solar panels can power spacecraft, cars and aeroplanes and when new cheaper versions of photovoltaic cells become available more energy could be generated from solar than from nuclear in the next 15 years.

If you're planning to build a new home, you can use some of the bigger aspects of building green. used or recycled building materials, you can lessen the impact that you have. You can also choose environmentally friendly insulation like recycled newspaper or cotton. Try using as many materials as you can that are refurbished and not new. Install heating systems that are powered by solar power and electrical circuits that require wind power, for example.

Wind Energy Press Interviews at APEC

Instead of perpetuating our dependence on dirty fossil fuel sources, as Conectiv proposed, New Jersey can displace the need for any new power plants by reducing energy waste and developing clean sources of energy like wind and solar power.

Solar National's power management experts will be available for press and analyst interviews throughout the conference. To schedule an interview before or during APEC, please contact Megan Carter at 408-721-6929, 408-930-7624 (cell) or at megan.carter@nsc.com.

Solar power utilizes the natural light to convert the sun's rays into usable 12V power. Converting the sun's energy to electricity involves the stimulation of a group of electrically connected cells in the panel. As displayed in figure S1, solar or photovoltaic cells are contained on a module. And modules are grouped together to make an array. Many times larger arrays are set to follow the path of the sun during the day to maximize the amount of solar energy collected. These groups of cells are made up mostly of silicon or other semiconductors, which have the ability to absorb a fraction of the light that hit these cells. A current is then created when electrons are stirred up from the energy of the captured light moving to the semiconductor. These currents are forced to flow in a certain direction, which allow for the transfer of this solar energy into usable power. How Solar Energy Panels Work
