The HPTA and HPCA series for DC/DC transformers applications

PREMO has developed a new range of high power inductors specially designed for the most demanding applications in the avionic sector. These new inductor series are the high power planar choke HPCA, and the planar transformer HPTA.

The HPCA Series offers inductance values of 2,5 and 4mH, and currents of up to 165 and 120Arms respectively (180 A and 132 A). These high current chokes have very good inductance stability against high temperature and very low profile due to its new design which allows reducing skin and proximity effects. The energy loss is 18W to 120Arms, and 9 W to 165Arms. For special applications, PREMO offers a custom made design to optimize the results and maximizing the performance in the final system.

Its compact design is achieved by connecting threded inserts in output terminals. This product has been designed according MIL- for power inductors and ESCC 3201/009.

The HPTA series (Hybrid Planar Transformer for Avionics) is able to manage power up to 3150W, with efficiency up to 99%, due to its design and its low losses. It is available with full-bridge and ZVT full bridge topology and it’s a specific solution for DC/DC transformers applications for 28V buses.

Key characteristics:

-    High range of operating temperature from -40º C to 90º C, with heat sink dissipation, with effective temperature up to 125º C

-    Storage temperature from -50º C to 170º C

-    Operating frequencies up to 150KHz

Due to the advantages of these inductors, they are recommended especially for these applications: DC/DC converters of 28 V, inverter, DC/AC converter high voltage buses, electronic control unit (ECU), control unit.
