... The main function of the three phase measurement IC is calculating the sum of the three phase active power (the arithmetic sum or the absolute value sum), and supplying the frequency signals proportional to the active powers. If the BL0952A/BL6513/BL6511 is configured to execute the arithmetic sum of the three active powers, the sum of the three-phase power is calculated as follows: P ...

... Moreover, in this case, the phases of the voltage channel and the current channel can be matched completely, and the performance when PF equal 0.5C or 0.5L is improved. In BL0952A/BL6513/BL6511, this structure is selected. Though it is given in the system specification that the ripple of the output signal is less than 0.1%, in real measure of BL0952A/BL6513/BL6511, the calibration output is very stable, and the ripple of the typical output signal is less than 0 ...

... By adjusting the external capacitor Cf, the phase error can be corrected. The phase error will affect the system gain when PF is 0.5, and bring error. The process of BL0952A/BL6513/BL6511 can ensure the consistent compensatory value. Power Supply Monitor The BL0952A/BL6513/BL6511 contains an on-chip power supply monitor.
