If the SCR fires immediately (at zero time, at the beginning of each cycle), then it is 'on' for a full 1/2 cycle (or a full cycle for a TRIAC). A full 1/2 cycle is the most time the SCR can be 'on' , so max. power is delivered.

The power delivered to the load is maximum when the SCR firing angle is at 90° ( or 270° ) .
Voltage and current are near maximum values at that moment in time.
Maximum deliverable energy occurs immediately following the zero crossing at 0° and 180°.

it will strengthen the final capability. by utilising reducing the firing attitude to 0 you're triggering the SCR previous to in case you waited for the ninety degree ingredient. 0 is on the commencing up of the sine wave the place the 0 pass ingredient is. ninety ranges is on the peak of the 1st a million/2 of the cycle. in case you positioned off at ninety ranges you basically have the relax a million/2 of the cycle (from ninety to a hundred and eighty ranges) for conduction. Triggering at 0 ranges the finished a million/2 of the cycle (0 to a hundred and eighty ranges) is carrying out.
