where I is the peak current,
between voltage and current.
Active power
In the STPM01, after the pre-conditioning and the A/D conversion, the digital voltage signal
(which is dynamically more stable with respect to the current signal) is processed by a
differentiated stage which transforms:
Equation 4
v(t) → v’(t) = dv/dt = V
The resulted signal, together with the pre-processed and digitalized current signal:
Equation 5
i(t) = I
are then available for the calculation process. These digital signals are also provided into
two additional stages which perform the integration of themselves, obtaining:
