The power supplied by the ac source is computed from AVG(W(V1)) as 444.6 W.
When ideal diodes were assumed, power supplied by the ac source was identical to the
power absorbed by the load, but this analysis reveals that power absorbed by the
diodes in the bridge is 444.6 425.4 19.2 W. Another way to determine power
absorbed by the bridge is to enter AVG(W(D1)) to obtain the power absorbed by diode D1 , which is 4.8 W. Total power for the diodes is 4 times 4.8, or 19.2 W. Better models for power diodes would yield a more accurate estimate of power dissipation in the
diodes.
