The reason for this is the discharging of thecapacitorin the Triac. The lamp dimmer circuits use a Diac to give a triggering pulse to the gate. So when the capacitor inside the Triac discharges through the Diac, the Backlash effect develops. This can be rectified by using a Resistor in se...
in the case that leakage voltage is flown from a work site, electricity is not conducted when the leakage voltage is less than a yield voltage of a diac, so a triac is not turned on and current is blocked from following ends to prevent detonation, thereby providing an effect of being saf...
In addition, when the leakage voltage is input from a working site, and the same is less than or equal to breakdown voltage of the diac, the conduction is not performed so the triac is not turned on. Thereafter, current is blocked to an end not to be initiated, thereby being safe ...
