Kinetis ^® KM3x_256 MCU three-phase electricity meter reference design

Overview

As electricity consumption continues to increase worldwide, especially in the residential market, power companies require more accurate and cost-effective meter solutions. The Kinetis ^® KM3x_256 Series Three-Phase Electricity Meter Reference Design increases energy measurement accuracy by providing a high-performance analog front end (24-bit AFE), combined with an embedded programmable gain amplifier (PGA), while also implementing a cost-effective shunt Sensing circuit, and low bill of materials (BOM) cost, meeting the dual needs of accuracy and cost.

This three-phase energy meter reference design is used for the measurement and registration of active and reactive energy within a directly connected three-phase network. It is pre-certified according to the European Class B and C specifications EN50470-1 and EN50470-3, as well as the international standards IEC 62053-21 and IEC 62052-11 for meters Class 2 and Class 1 active energy.
