ADE7753
From Equation 19 it can be seen that there is a small ripple in
the energy calculation due to a sin(2 ωt) component. This is
shown graphically in Figure 68. The active energy calculation is
a lower output frequency at CF for calibration can significantly
reduce the ripple. Also, averaging the output frequency by using
a longer gate time for the counter achieves the same results.
shown by the dashed straight line and is equal to V × I × t. The
sinusoidal ripple in the active energy calculation is also shown.
Since the average value of a sinusoid is 0, this ripple does not
contribute to the energy calculation over time. However, the
ripple can be observed in the frequency output, especially at
higher output frequencies. The ripple gets larger as a percentage

of the frequency at larger loads and higher output frequencies.
The reason is simply that at higher output frequencies the

sinusoidal ripple is observable in the frequency output. Choosing
