Abstract

This application provides a planar transformer and an active circuit, applied to a telecommunications device and a communications power supply in fields such as a 5G mobile communications technology and cloud computing. The planar transformer includes a winding structure and a magnetic core structure. The winding structure includes a primary-side winding and a secondary-side winding. The magnetic core structure includes a first magnet part, a second magnet part, and a plurality of magnetic cylinders. The plurality of magnetic cylinders are located between the first magnet part and the second magnet part. The primary-side winding is wound around M magnetic cylinders in the plurality of magnetic cylinders, wherein M is a positive integer equal to or greater than three (3). A cross-sectional area of at least one of the M magnetic cylinders is different from a cross-sectional area of another magnetic cylinder.
