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.
Leyden Energy partners for wireless charging News & Analysis 1/10/2012 Post a comment Battery technology startup Leyden Energy said it is teaming with Powermat Technologies, a developer of wireless charging technology, to develop high-density battery cells and packs based on Leyden’s core Li-imide salt technology.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
