6. The simulator s power supplies must not suppress this ripple as a function of their regulation loop An increasing number of inverters and virtually all micro inverters accurately measure amplitude and phase of the ripple voltage and current to quickly track the MPP of the array This approach allows tracking the MPP at a much higher speed when compared to conventional dithering techniques also called perturbate and observe Faster tracking of the MPP results in a much higher overall efficiency in cloudy conditions where the irradiance is constantly changing It is likely that all solar Available Q4 2013 858 458 0223 AJ i ETHERNET inverters will use this approach in the near future since end users are very sensitive to the overall efficiency of their solar energy installations To satisfy this requirement the PV simulator must be capable of reproducing the voltage current behavior of a solar array at the ripple frequency Most standard switching power supplies employ very large output capacitors and inductors in their output circuits and are unable to deliver the required performance regardless of the response speed of the l V curve controller Elgar s TerraSAS line of PV simulators are based on high speed versions of our standard products where output capacitors and other speed limiting components have been adjusted This results in a speed improvement of 10 times or better Proprietary features b
