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 ...

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 ...

More and more portable devices now use ceramic capacitors for filtering of dc/dc-converter inputs. Ceramic capacitors offer the advantages of small size, low ESR (equivalent series resistance) and ...

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 ...

Overload prevention in any given design is serious business, which means that the choice of safety capacitor shouldn’t be taken lightly either. Areas to consider in the decision process include safety ...
