Wound-rotor transformer and power source device using said wound-rotor transformer

a a b b a a An object of the present invention is to materialize a small size wound-rotor transformer in a simple structure, wherein the primary winding is mounted on the central portion of the bobbin (insulator) , and the first and second secondary windings are mounted at both sides of the primary winding . The lead wire of one end of the first secondary winding is connected to the secondary high tension terminal of the first terminal unit , and the lead wire of one end of the primary winding and the lead wire of end portion of the winding at the side in contact with the primary winding of the first secondary winding are respectively connected to the corresponding primary input terminal and the ground terminal of the first terminal unit . The lead wire of one end of the second secondary winding is connected to the secondary high tension terminal of the second terminal unit, and the lead wire of the other end of the primary winding and the lead wire of the end portion of the winding at the side in contact with the primary winding of the second secondary winding are respectively connected to the corresponding primary input terminal and the ground terminal of the second terminal unit . The core is mounted on the bobbin (insulator)
