The magnetic pulse welding is peculiar technology using large electromagnetic force. Pulse large current flowing through the flat one-turn coil is produced this large electromagnetic force. However, there is only using the spark gap switch for discharged the capacitor energy, since the pulse current exceeds 100kA. The spark gap switch needs the maintenance in the every discharge. Then, the transformer is introduced in order to reduce the current, apply the semiconductor switch. In this study, the air core transformer of 2:1 turn ratio was made, and the primary current was reduced in about 1/2. It was possible to produce the transformer of the very high coupling coefficient by the proposed production method. |
