PREMO presents its planar transformer for the automotive market

The new PREMO planar transformer for automotive is an innovative solution for the automotive market that accomplish specific sector standard, AEC Q-200. It has been formerly conceived for ISG systems. However, it is a versatile product that can be used in DC/DC converters and traction inverters in hybrid vehicles. It has been developed under a unique vacuum potting technique that allows a high isolation level (10kV).

Among its main features stands out its high power management (1.7kW to 5kW) in a 3.3cm height profile and less of 100cm2 room area. Product is presented within a shell shaped aluminum heat sink. This shape allows an isotropic heat transfer that increases component's performance. Laminated inner design allows a high efficiency: Rated losses are below 1% of total output power and effects such as skin and proximity have been considerably reduced. PREMO has developed a mechanical fastening system on it in order to improve final assembly structure in front of mechanical stress tests according the most stringent standards. Selected raw materials constitute a high temperature resistant system up to 180ºC.

PREMO is present in automotive customers since 1996, with transponders coils for immobilizers, TPMS and passive entry applications. The new development for power transmission platforms for hybrid vehicles increases the quantity of power electronics inside the cars, expanding the use of PREMO inductive components.

PREMO has been developing planar transformers for 20 years and covers the widest range in the market from the low power units up to high power ones (10kW). PREMO has one of the best planar tech expert team in the world, based in PREMO Headquarters in Barcelona. Standard PREMO planar transformer group includes more than 50 different types. Special mention to NS-Series for low power applications in the telecommunication market harmonized with National Semiconductor's controllers.

They manufacture and design inductive components, EMC filters, RFID components, power transfo and systems; and PLC accessories and components.
