The need for conditioning low-level ac signals in the presence of both common-mode noise and differential dc voltage prevails in many applications. In such situations, ac-coupling to instrumentation ...

Around the world, over 200 countries use Alternating current (AC) power as a convenient power source for many electronics. However, the power around the world is not the same in each location, ...

Programmable AC power sources have been widely used to implement and support numerous product test procedures over the years. They provide the test engineer with the ability to fully control voltage, ...

Worldwide ac mains voltages can range from 100 to 240 V. To allow for sags (brownouts) and surges, offline ac supplies intended for universal input are rated at 85 to 165 V. The ac frequency ranges ...

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 ...
