Ultrasonic transducer driver 1. However, during an ESD event across the domains, one would want a path for the high current to traverse.
Dec 248: Welcome to our site! It is in fact, neither anti-parallel, parallel, nor series.
Use of anti-parallel diode in ESD 2. SCR will get triggered when gate current reaches to trigger level. Regardless, this sounds like homework. The pulse triggering as indicated in the drawing of OP has a high frequency in respect to the mains frequency and is required in cases of inductive loads triggering failure due to Back EMF from DC motors.

How about connecting natiparallel MOC optotriac like this: Thank you very much for the patience and your extremely cooperative replies. Please advice on how to proceed from here on.

One example is the TRIACwhich is comparable to two thyristors connected antiparallep in other words, reverse parallelbut on a single piece of silicon. Battery-powered lights, which are wired in parallel, can also create a simulated “chasing” effect by alternating the polarity for each LED attached to the string, and controlling the positive and negative parts of the cycle separately.
You must log in or register to reply here. By eliminating the need for extra wires, this reduces costs for the manufacturer, and makes the cords less bulky and obvious for the consumer to string xntiparallel decorative items. If the flickering problem is related to antlparallel current limitation, then flickering will be gone if we increase the value of to say ohms or 1k. By ‘danger’ I meant ‘misfiring’ that could damage the thyristors.
There are downsides using triacs vs this arrangement. It is safe to use pulse train triggering. Actually pulse train triggering is the only way to handle inductive loads with thyristors or triacs.
I had connected a bulb to the anti-parallel scr to test the functioning.
