Single-Phase Energy Meter Solution for Advanced Applications
This design features a dual-core microcontroller implementing an integrated electricity metering solution. The meter has been tested to prove 0.5% accuracy across a current dynamic range of 2000:1 by using a precision, low-noise op-amp and a programmable gain amplifier (PGA) to provide four gain stages. The metrology calculations are performed independently of the MCU integrated cores, leaving both MCUs available for other applications, including Power Line Communications (PLC). Developers will benefit from this design by taking advantage of both the ARM® Cortex®-M3 and C28x MCUs to provide the e-meter host applications and PLC communications.
Power Line Communications (PLC) System-on-Module for ARIB Frequency Band
The SOMPLC-F28M35 is a single-board System-on-Module (SOM) for PLC in the ARIB frequency band. This single hardware design supports several popular PLC industry standards, including G3 and IEEE-1901.2. TI's certified PLC software is available along with the SOMPLC-F28M35. Engineers can take the SOM design and integrate it into their overall system board or keep the design as an add-on board to their application. The only additional hardware required is the AC mains line coupling circuitry. The included hardware schematics and Gerber files simplify the task for engineers to add PLC to their end system. OEMs will benefit from having the ability to rapidly evaluate and prototype PLC technology in their application.
