The paper considers the architecture and low power design aspects of the digital signal processing block embedded into a three-phase integrated power meter IC. Utilized power reduction techniques were focused on the optimization of control logic block. The operations that control unit performs are described together with power optimization results.

The STEVAL-IPE006V1 is an integrated system designed to provide a complete demonstration of a high-end solution for power metering. It shows no compromise measurement of active, reactive and apparent energies, load management and automatic meter reading via a power line modem, antitampering both on neutral wire and meter box, surge protection and in-application programming. The demonstration bo...

ZigBee is a new global standard for wireless communications with the characteristics of low-cost, low power consumption, and low data rate. It has a good market in wireless meter reading. The design and implementation of a ZigBee-based wireless automatic meter reading system are proposed in this paper. The experimental results show that the design can meet the basic needs of automatic meter rea...
