Kepco announces an option for its 200W and 400W BOP models to optimize their
ability to drive capacitive loads. This option (designated by the suffix "C")
makes the BOP more suitable for a wide variety of applications such as solar
cell/panel testing, testing of piezoelectric devices, capacitor testing,
driving and testing of capacitive transducers, and powering industrial or
lab-type applications with capacitive or capacitive-resistive loads.
BOP C option units are designed to operate in a stable
manner in Voltage or Voltage Limit mode for capacitive loads up to 10
millifarads. They are also stable when driving any R-C parallel combination
where load R is > or = to nominal value and C is < or = to 10mF. Load R
(nominal value) = nominal output Voltage/nominal output Current (e.g., BOP
36-6MC, R = 36/6 = 6 Ohms.) Static specifications representing accuracy for
various influence parameters are identical to the standard BOP models. Ripple
and noise specifications are better (approximately 50 percent lower) for the C
option units compared to the standard BOP. Six models (ranging from 20 to 100V
source/sink capability) are available at present. Three additional models are
expected to be available in the coming months.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
