Planar Transformer targets automotive market

[2008-7-15]

Tag: Used Transformers

Featuring power management of 1.7-5 kW in 3.3 cm height profile and occupying less than 100 cm², PREMO planar transformer meets AEC Q-200 standard. Developed under vacuum potting technique that allows for 10 kV isolation, it can be used in dc/dc converters and traction inverters in hybrid vehicles. Unit is available in shell shaped aluminum heat sink which enables isotropic heat transfer, and has rated losses below 1% of total output power.

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.
