Hi All,
Please tell me how to convert power factor to voltage.
 

Hi,

what input signals?
3 phase, single phase?
sinusoidal shape or any shape?
linearity, precision?
What input voltages and what output voltage?
purely analog design, or with ADC and ucontroller?

Hi,
Voltage and Current, single phase, sinusoidal shape, output from 0V for 0.5 lead to 5V for 0.5 lag,purely analog design
 

Hi

No linearity needed...

Then you simply can use two comparators with threshold at 0V.

XNOR both signals.

Lowpass filter the XNOR output
Levels of 0V up to 2.5V are valid
0V: cos(phi) = 1, 0 degree
2.5V: cos(phi) = 0, 90 degree

The output is linear to degrees phase shift. 0 to 90 degree. Not linear to cos(phi).
