Pulselarge current flowing through the flat one-turn coil is produced this large electromagnetic force. However, there is only using thespark gap switch for discharged the capacitor energy, since the pulse current exceeds 100kA. The spark gap switch needs themaintenance in the every discharge. Then, the transformer is introduced in order to reduce the current, apply the semiconductorswitch. 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 waspossible to produce the transformer of the very high coupling coefficient by the proposed production method.}, pages = {17--20}, title = {電磁圧接および電磁成形用空芯トランスの特性}, volume = {4}, year = {2010}, yomi = {イシバシ, マサキ and オカガワ, ケイゴ and アイザワ, トモカツ and ヘンミ, ノブオ} }
