Abstract
A primary winding connected to a high-voltage, a large-current power supply , a secondary winding connected to an electromagnetic forming coil , and a magnetic core for guiding the magnetic flux produced by the primary winding. The magnetic core is composed of a primary core on which the primary winding is wound and a secondary core on which the secondary winding is wound. The primary core and the secondary core are magnetically connected in contact or in close proximity. The primary core and the secondary core are separated each other when the connector is disconnected. Thus, current pulses at a high voltage (for instance, 10 kV) with a large current (for example, 100 kA or more) and a narrow pulse width (e.g., 30 &mgr;sec or less) can be efficiently transmitted, and the connector easily attached and removed.
