Their job is to convert high-voltage alternatingcurrent from the mains into low-voltage directcurrent for mobile phones, laptops, iPods and other electronic gadgets.
Since 2005, the company has stood out in the fast-moving LED industry with an innovation that allows LEDs to be powered by alternatingcurrent, or AC, rather than requiring a transformer that turns AC into directcurrent.
Traditional inverters gather power from all or most of the panels in an installation and use transformers, capacitors and switches to change it from directcurrent to alternatingcurrent.
They can carry five to 20 times more current in the same unit area while reducing the amount of energy lost as heat by 75-97% (depending on whether the current is alternating or direct), even after accounting for all the nitrogen-cooling paraphernalia.
Yet it's scarcely visible in the market for solar panel inverters, devices that turn the directcurrent power generated by solar panels into alternatingcurrent for the grid.
These devices transform the directcurrent generated by a solar panel or electric car battery into the alternatingcurrent you expect from a wall socket.
