The TIDA-00601 design uses isolated shunt sensors to implement a Class 0.5% three-phase energy metering system. Isolation is achieved by using an isolated Delta-Sigma modulator with a capacitively isolated output circuit. The energy metering SoC takes different bit streams from the isolated modulator and uses its onboard digital filter to generate ADC sample readings. The energy metering SoC is also used to sense voltages, calculate metering parameter values, drive the board LCD, and communicate with the PC GUI via the board's isolated RS-232 circuitry.
Flyback converters are the preferred topology in the SMPS (switched-mode power supply) for medium- and low-power range applications because they are simple and economic. They have less components and are efficient in isolating the output from input. They are used in battery-powered applications, universal AC/DC converters, and industrial and telecommunication equipment. Isolated converters traditionally regulate the output voltage and current by utilizing a secondary side regulation (SSR) composed of an optocoupler and secondary error amplifier.
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.

The Energy Monitor is designed as a complete set of tools for measuring and displaying the energy consumption of individual loads within a smart building, such as major appliances. This tool allows engineers to quickly evaluate TI's solutions for low-cost energy metering applications. The reference design comes with hardware and software design files to speed engineers' development process. The energy monitor design can also be expanded to integrate with TI's ZigBee and Wifi reference designs to add wireless communication capabilities to the end product.
