Answer Posted / joy das gupta
In X-former two losses- Cu loss and Iron loss.Hence Cu loss
depends on Current(A) and Iron loss depends on
Voltage(v).There is no phase angle between them. Again in
the output side of the X-former, we don't know the types of
load(Inductive , Capacitive, Resistive) which is connected
with secondary coil. Though it is not, we cant fixed the
power factor and it can vary. So under consideration of
losses and avoid the load pf variety, the transformer rating
given in KVA.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
