In Equation 5, a harmonic real power component is generated
for every harmonic, provided that harmonic is present in both
where:
i(t) is the instantaneous current.
I 0 is the dc component.
I h is the rms value of Current Harmonic h.
β h is the phase angle of the current harmonic.
Using Equation 2 and Equation 3, the real power, P, can be
expressed in terms of its fundamental real power (P 1 ) and
harmonic real power (P H ) as
P = P 1 + P H
where:
P 1 = V 1 × I 1 cos ? 1
? 1 = α 1 ? β 1
and P H
∞
P H = ∑ V h × I h cos ? h
h ≠ 1

the voltage and current waveforms. The power factor calculation
has previously been shown to be accurate in the case of a pure
sinusoid. Therefore, the harmonic real power must also correctly
account for the power factor because it is made up of a series of
pure sinusoids.
Note that the input bandwidth of the analog inputs is 7 kHz at
the nominal internal oscillator frequency of 450 kHz.
