When the Power Fails: Designing for a Smart Meter’s Last Gasp
Design How-To  
1/10/2012   5 comments
A smart meter is powered by the same bus the meter is monitoring. When power is lost, the meter must record state information to flash memory or send out a wireless signal -- the meter’s last gasp. The problem of efficiently and cost-effectively providing hold-up energy typically falls to power supply designers. Try one of these flyback switch mode designs to provide for that last gasp.
