The quality of electricity drawn from the public grid is
surprising poor due to both less than ideal power factors as
well as distortions, i.e. noise. The US Department of Energy
estimates that 70% of the electric motors in the US operate on
less than an ideal power factor. 3DFS™ estimates that the
typical home operates at a power factor worse than 0.7. In
addition the total harmonic distortion (“THD”) of the
electricity typically supplied by the public grid is
approximately 10 to 20%, versus a clean power threshold of 6.0%.
The 3DFS™ Power Controllers deliver power with a THD under 0.1%.
Despite the decrease in efficiency caused by distortions in the
power supply (as best measured by THD), almost no utility
regulators across the world set targets for THD in the power
supply. The new standard in clean power set by 3DFS™ allows for
electronics to operate much more effectively as well as waste
less power. Similarly power factors are largely ignored in the
residential electricity market where utilities in the ab
