<P>PROBLEM TO BE SOLVED: To provide a high-frequency quenching device employing a current type inverter structure more expedient than serial resonance and capable of eliminating a floating phenomenon of a matching part causing a problem of a conventional current type inverter structure, and effectively and alternately heating heating objects. <P>SOLUTION: This current type inverter device includes first and second current type inverters 21b and 21b' and is so structured as to alternately oscillate the first and second current type inverters. The current type inverter device is provided with: loop circuits 7b and 7b' having D.C. power sources 6b and 6b' in the circuits; two bridge circuits 11b, 12b, 11b' and 12b' connected to the loop circuits and having switching elements 9b and 9b' and reflux diodes 10b and 10b', respectively; lead wires connected to the two bridge circuits, respectively, and connected to the primary side of a matching transformer; and resistors arranged in a line connected to the lead wires and the loop circuits. <P>COPYRIGHT: (C)2007,JPO&INPIT |
