The Flat Transformer is the first technological breakthrough in transformer technology in the last 60 years. It overcomes the limitations of a conventional transformer, such as hot spots due to poor heat dissipation, high leakage inductance, poor high frequency characteristics, tedious manufacturing process and bulkiness in packaging. These cores are packaged in a modular block with built-in single turn secondary winding using simple, stamped and formed parts. The modular blocks are mass produced which further reduces the costs.
Modular blocks offer great flexibility in design.
In addition, parasitic impedance can be better controlled which results in less snubbing and less stress on ancillary parts. Hot Spots are eliminated as individual elements in Flat Transformers are small with high surface to volume ratio. Thermal paths are short. Build-up of bulk windings does not exist. With excellent heat dissipation, higher flux densities can be used.
