FUNCTION DESCRIPTION:
BL0935 is designed to compute the active power and electrical energy of trio-Phase(including the dual-phase
and single-phase).It provides a pulse output proportional to the sum of trio-phase active power as well as pulse
used to drive dual-phase stepper motor .The influence of various phase power should be counted in when
computing the power dissipation and electrical energy.Consumption of energy is determined by the power
measurement being integrated over timeless than 0.3% Error over a Dynamic Range of 200:1.
Trio-phase power computation : P=Ga* Iv1*Ii1 + Gb* Iv2*Ii2+ Gc *Iv3*Ii3
Where:
Iv1,Iv2,Iv3:the sampling value of tri-phase voltage
Ii1,Ii2,Ii3:the sampling value of tri-phase current
Ga,Gb,Gc:the gain of the trio-phase power multiplier
FP: frequency of output pulse : Ffp = k*p/3*Ir2
Where:
Ir: reference current
K: constant of frequency conversion
