Premo develops new technology for high power planar transformers

To manage increasing output current levels of power converters, Premo has developed a new technology using planar transformers within a extended power range (few kW to 10 kW). This technology is specially developed for full-bridge topology with a high input voltage level (500-1000V) achieving different turns-ratio of 2 :1, 3 :1… Switching frequency can be defined between 70 to 160 kHz.

Typical applications are power systems for machine-tools, laser cutting or punching systems, as well as special apparatus for medical appliance.

This new range of components completes the P264 family (multilayer printed-circuit-board technology) dedicated to industrial applications and the HPC / HPT series (overmolded products) fitting the next automotive platforms for hybrid and electrical vehicles.
