Planar transformers<\/h2>\n\n\n\n

What is a planar transformer?<\/h3>\n\n\n\n

Planar transformers are transformers used in isolated switch mode power supplies operating at high frequency. The transformers consist of stacked turns of copper foil (105\u00b5m or 210\u00b5m thick foil) connected to each other using multilayer technology. The planar transformer PCB designer increases the power of this type of PCB. The circuit range can be up to 24 copper layers depending on the design.<\/p>\n\n\n\n
