<p>PURPOSE:To suppress the surge voltage generated upon opening of the GTO of a snapping circuit by connecting directly the anode of the GTO and a diode, as well as a capacitor and the cathode of the GTO, thereby reducing a wiring part. CONSTITUTION:A GTO1 is interposed between cooling fins 5 and 5', and uses the fins 5, 5' as electrodes. A diode 2 is mounted directly on the fin 5'. A capacitor 3 is constructed to commonly use one terminal of an aluminum case, and is intimately contacted (or buried) with the fin 5. Since the GTO1 and the diode 2 as well as the GTO1 and the capacitor 3 are connected via the fins 5, 5', connecting wires are not necessary, thereby enabling to shorten the wire of a loop of the GTO-diode 2- capacitor 3-the GTO.</p> |
