Abstract
The invention relates to a transformer () with a planar primary winding and a planar secondary winding. In order to support the heat dissipation during operation, each winding is integrated on a substrate in at least one dedicated PCB (). The PCBs () are separated from each other by a non-ferromagnetic and electrically insulating material (). The material: () transfers heat better than the substrates. The invention relates equally to an apparatus comprising such a transformer ().
