Do you require a power system to analyse the electrochemical properties of your energy storage device? Maybe you need to characterise switches at high speeds? Perhaps your existing PSU isn’t dynamic enough to cope with your component’s transient response demands? Our DC systems could be the catalyst your testing needs...
The G5 series allows users to program a current ripple up to 10kHz for EIS research. The units are able to output both the DC operation point and the modulated sinewave signal as a single output. So there is no need for external modulators or other equipment. This results in a high quality signal quality with no interferences from other power electronics. Particularly important if your test bench has fieldbus communication interfaces susceptible to noise.
Any AC signal superimposed on the DC current should be as small as possible. This ensures a time-invariant system which behaves linearly, necessary for further EIS analysis. The levels of voltage response of a device under test need to be high enough to be measured adequately. This comes down to a good signal-to-noise ratio (SNR). Typical values are up to 5% of the main DC current level, which is easily within the G5’s capabilities.
