Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This one, concerning power factor correction capacitors and how to calculate their kVAr, is answered by ABB ...

Abstract: The layout area and power consumption of a charge-scaling digital-to-analog converter (DAC) is typically dominated by the capacitor array. For a binary-weighted DAC, since the number of unit ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Building a capacitance meter is a great exercise. If you’re feeling quite safe in your digital-circuit-only life, this will push just far enough out of the comfort zone for you to see there’s nothing ...

University College, The Pennsylvania State University, York, USA. Figure 1 displays the pictorial foundation of this investigation. Its left panel shows two different-sized nonconcentric “infinitely” ...

Abstract: Graphene has been much anticipated as an ideal active material of electric double layer capacitor (EDLC). However, the overall capacitance of monolayer graphene is affected by its own low ...
