Industrial AC/DC power supplies must convert mains voltage to regulated DC under strict efficiency mandates, such as 80 PLUS, tight EMI/EMC limits, safety isolation requirements, and compact-enclosure thermal constraints. All of this must be done while surviving inrush, transient, and overload events over long duty cycles.
Vishay offers products for the full power conversion chain. Our high voltage SiC MOSFETs minimize switching losses. THB graded X1/X2/Y2 film capacitors and AC-line-rated ceramic disc capacitors provide EMI filtering and safety isolation, while power inductors help reduce electrical noise and DC-Link capacitors deliver bulk energy storage. Vishay's fusible wirewound safety resistors provide overcurrent protection, and NTC thermistors limit inrush current. Vishay allows designers to source nearly all of an AC/DC PSU BOM from a single supplier.
