    Could anyone explain the conduction angle n firing angle in the case of thyristors (SCR) and the relation they share...??:confused:

    What do you mean by "conduction angle" and "firing angle"?

    Perhaps he's talking about phase angle control in SCR light dimmers and the like.

    If so, I guess the firing angle would refer to the number of degrees at which the SCR "fires" (is triggered), relative to the start of the half-cycle, and the conduction angle would refer to the total angle for which the SCR conducts.

    In that case, firing angle + conduction angle = 180 degrees (roughly - because the SCR will drop out slightly before the end of the half-cycle due to insufficient holding curent).
