Study on Poly Phase Multifunction Energy Metering IC

ADE7758, ATT7022B and MAXQ3180 are three kinds of Three-phase multifunctional energy metering IC. In the first place, this paper gives an introduction of the three chips on theory of operation. After that, particular contrast is carried out on performance. Finally, the conclusion is summarized. ADE7758 supplies per phase information, but it does not supply power-factor, phasor or three-phase information, ATT7022B supplies the most per phase and three-phase information, but it does not offer the function of interrupt, MAXQ3180 can not only provide the per phase, phase combined power-related parameters and harmonic measurement function, but also has the function of abnormality judge. The conclusion above can be used to select a right energy metering IC on the project.
