Embedded digital control facilitates adaptive power control strategies Design How-To 1/31/2012 Post a comment Able to swap seamlessly between utility ac line and local battery backup power, the intermediate-bus architecture (IBA) that the telecoms industry has refined over decades to become cost-competitive with traditional offline-only sources is an attractive alternative for system architects needing high availability in a wide range of industries. New developments in areas such as intelligent power management strengthens the arguments in favor of the IBA.
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.
