PRODUCTION DATA
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.
The following resources provide application guidelines and best practices when designing with the MSP430i20xx devices.
This application report describes the implementation of a low-cost 1- or 2-phase electronic electricity meter that uses the TI MSP430i20xx metering processor. This application report includes information on metrology software and hardware procedures for this single-chip implementation.
Single-Phase and DC Embedded Metering Power Using MSP430i2040 application report
This application report describes an EVM that uses the MSP430i2040 microcontroller for embedded metering (submetering). In this application, the electricity measuring device is embedded in the end application and gives the user information about the voltage, current, and power consumption of the device. In addition, the EVM can compensate for line resistance and EMI filter capacitance.
Single Phase and DC Embedded Metering (Server Power Monitor) reference design
This reference design implements a high-accuracy single-phase embedded meter using an MSP430 MCU. This EVM has built-in support to measure AC voltage, current, active power, reactive power, apparent power, frequency, power factor, voltage THD, current THD, fundamental voltage, fundamental current, fundamental power and DC voltage, DC current, DC active power. It can detect the input voltage to work in DC or AC mode. It can also compensate for the effects of the wire resistance and the EMI filter capacitance so that the reading of voltage and power matches the reading of an external meter when EMI filter is connected to the input.
Three Output Smart Power Strip reference design
This reference design implements a high-accuracy single-phase embedded metering smart power strip using an MSP430 MCU. This design supports measurement of AC voltage, current, active power, reactive power, apparent power, frequency, and power factor with 3 sockets measured individually. Additional hardware is added to provide futher development like relay control and wired or wireless communication.
