Preliminary Technical Data
HPF AND OFFSET EFFECTS
Figure 27 shows the effect of offsets on the active power
calculation. An offset on the current channel and voltage
channel contributes a dc component after multiplication as
shown in Figure 27. Since this dc component is extracted by the
LPF and is used to generate the active power information for
each phase, the offsets can contribute a constant error to the
total active power calculation. The HPF in the current channels
avoids this problem easily. By removing the offset from at least
one channel, no error component can be generated at dc by the
multiplication. Error terms at cos(ωt) are removed by the LPF
and the digital-to-frequency conversion (see the Digital-to-
Frequency Conversion) section.

Figure 27. Effect of Channel Offset on the Active Power Calculation
The HPF in the current channels has an associated phase response
that is compensated for on-chip. Figure 28 and Figure 29 show the
phase error between channels with the compensation network.
The ADE7762 is phase compensated up to 1 kHz as shown. This
ensures correct active harmonic power calculation even at low
power factors.
