Payton Planar Magnetics Introduces Line of Low Profile High Power Transformers

March 03, 2011 by Jeff Shepard

Payton Planar Magnetics introduced a new line of low profile high power transformers. The transformer is the key to the efficiency of a power supply. With the low leakage low loss techniques of planar technology, Payton is making available high power transformers with 99%+ efficiencies. These types of transformers are used in battery charging stations for HV and can be connected in series to achieve 60-80KW. All Payton automotive magnetics are qualified to meet full automotive specs.

Any power loss in the transformer is a non-recoverable loss and a major contributor to the efficiency of the power supply. Payton Planar transformers have 99%+ efficiency and can improve the overall MTBF of a system by effectively reducing the internal temperature rise of the components. The 8kW design pictured below has less than 50W of dissipation at full output power of 32V and 250A and with conduction cooling the temp rise is less than 60°C. The transformer is designed for 270V input voltage and 2000 V/usec operating volt-sec. Size is 140 x 90 x 35mm and 8000W of output power the power density is 300W per cubic inch.
