Abstract
PURPOSE: To enable an operation of correct firing, by means of amplifying a differentiation pulse in the differentiating circuit through a pulse transformer to make a firing of the triac.
CONSTITUTION: If applied a collector output of switching transisitor TR to a differentiating circuit C2, R5, a differentiation pulse will be outputted from the differentiating circuit C2, R5, as shown by a wave form Vc in the drawing. With this output amplified by a pulse transformer T2, a triac TC is turned on. In such way, a firing of the triac comes to be correctly operable
