IEC Compliant Active-Energy Meter Design Using the MCP3905/6

From Microchip Technology, Inc.
 

 
The MCP3905/6 energy-monitoring Integrated Circuits (ICs) supply active real power measurements for single-phase residential meter designs. These devices include features specific for the International Electrotechnical Commission (IEC) requirements, such as no-load threshold and start-up current. In addition, the MCP3905/6 Energy Meter Reference Design demonstrates a system-level design that passes EMC immunity requirements per the IEC standards. EMC testing for the IEC compliance was performed on the Energy Meter Reference Design Demonstration Board used in this application note. These tests were performed by a third party, the results of which are included at the end of this application note.
