Abstract
A transformer is disclosed, including a magnetic core, a bobbin, a primary winding wound around the bobbin, at least a first secondary winding and a second secondary winding and at least one turn of coil of the first secondary winding is adjacent to at least one turn of coil of the second secondary winding, and the first secondary winding and the second secondary winding are applied in a full-wave rectifier circuit. A leakage inductance groove is provided between a primary winding groove for winding the primary winding and a secondary winding groove for winding the secondary winding for isolating the primary winding and the secondary winding.
