Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

In order for the solenoid point motor to throw the point we need to apply current briefly to an electromagnetic coil. A capacitor discharge unit greatly improves reliability in that it builds up and ...

Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

Why is Power Factor important? The phase relationship between the ac-power-line voltage and current is related by a term called power factor. For a purely resistive load on the power line, voltage and ...
