Abstract
PURPOSE:To prevent a malfunction although the superposition of time occurs in a driving pulse, by avoiding the generation of an output at the secondary side in case two pulse transformers are driven at one time. CONSTITUTION:When the driving pulse is applied to a terminal 14 or 24, a transistor TR is turned on to flow the current to the primary side winding of a pulse transformer. As a result, a TR15 or TR25 with the base terminal connected to the secondary side winding is turned on. When the driving pulse is applied to both terminals 14 and 24 at one time, the current flows to the primary side winding of both pulse transformers 10 and 20. In this case, both the current flowing to the 3rd side winding 13 of the transformer 10 and the 3rd side winding of the transformer 20 are turned forward. As a result, the impedance of the 3rd side winding becomes zero when it is viewed from the primary side winding to flow no current to the secondary side winding.
