Planar Introduces Automotive Planar Transformer in Small Package

Payton has introduced a line of automotive grade Power Planar Transformer available for use in the harsh automotive environment. The transformer is designed to accept 400Vdc input from a pfc, and provide battery charging voltage on the output at 200A. The total output power is 3000W provided the transformer is mounted on a 90°C cool plate. The clasp allows an easy way to thermally and mechanically secure the transformer to a cold plate.

Switching frequency is 186Khz and the topology is Full Bridge . The total area volume needed is under 6 in³ and the power density is 500 W/in³. The efficiency is better than 99% Different models can be designed in this configuration based on specific technical requirements. Additional models are available with different pin configurations.
