Providing active balancing for series-connected batteries Design How-To 4/23/2013 2 comments Large battery stacks are commonly used for EVs and power grids, and lithium polymer or LiFePO4 cells are often selected for their high energy density and high peak power capability. However, Linear Technology notes that series-connected battery stacks present an additional requirement: cell balancing.
3-phase transformers made rugged Product News 4/18/2013 Post a comment Modular IPI Three-Phase Transformer Series from Innovative Power, Inc., delivers superior power management in a wide range of instruments and controls designed for heavy-duty industrial use.
Providing power for robotic surgical systems Product How-To 4/10/2013 Post a comment Robotic surgical systems allow for minimally evasive major surgeries. Powering these systems with distributive power architecture enables the use of a 48V nominal battery backed up bus voltage that powers downstream point-of-load regulators for all subsystems.
Tips for increasing oscilloscope vertical resolution - Part I Design How-To 4/4/2013 1 comment Measurement of small signals can be challenging as the ability to view them is impacted not only by the noise of the scope, but also by scope settings and probing. Agilent presents techniques to help your scope show smaller signals than you’ve previously seen with it.
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.
