EMI/EMC Compliant Meter Design with the 71M6511


摘要 : Designing a meter for optimum electromagnetic compatibility (EMC) can be a challenging issue for any design engineer. This application note discusses electromagnetic interference (EMI)/EMC compliance, based on Teridian's 2-layer 71M6511-DB, a demonstration board that evaluates single-phase energy-metering ICs. EMC/EMI testing for metering products involves conduced and radiated emissions, RF immunity, electrostatic discharge (ESD), and electrical fast-transient (EFT) testing. The methods discussed in the article provide EMI suppression without affecting meter accuracy.
