Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...
Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
Total power lost due to chip leakage is an increasingly important IC parameter. One of the most common methods of reducing it is to use a multiple-threshold CMOS (MTCMOS) cell to turn the power supply ...
