THREE-PHASE-POWER-METER: Three Phase Power Meter Reference Design
The Three Phase Power Meter Reference Design provides the example for implementing Three Phase Power Meter using Kinetis® M series MCUs. With the growing consumption of energy worldwide, particularly in the residential market, utility providers need increasingly accurate and cost-effective energy metering solutions. Three-phase electricity meter reference design addresses these accuracy and cost needs by providing a high-performance analog front end (24- bit AFE) combined with an embedded programmable gain amplifier (PGA) to increase the accuracy of energy measurement, along with a cost-effective shunt sensing circuit implementation and bill of materials (BOM).
