。[Claims for Utility Model Registration] DC input is switched on the primary side, the output thereof is added to the primary winding of the transformer, and the output of the secondary winding of the transformer is rectified and smoothed to obtain a DC output. Used in switching power supplies that detect and control overcurrent flowing on the next side. The transformer uses a magnetic core having a central leg and an outer leg located around the central leg, and the central leg is provided with a primary winding and a secondary winding for a transformer. At the same time, a current detection winding is applied only to the outer leg of the magnetic core to form a magnetic path in order to detect the differential component, and the outer leg of the magnetic core is used for transformer and current detection. A switching power supply transformer with a current detection section, which is characterized in that it can be used in common with the following.
