When it comes to the world of AC drives, there are two variations on the topic of noise: audible noise, typically generated by cooling fans, and electromagnetic noise emanating from the AC drives on various frequency bands.…
A few months ago, I read in the newspaper that an important supermarket chain in France had removed several batches of burgers after detecting traces of the bacteria Escherichia coli (E. coli). This bacteria causes quite a…
It was some years ago, while working in Danfoss Solar Inverters, when I had first-hand experience of how dramatically corrosion can affect AC drives. I visited a grid-connected photovoltaic plant consisting of multiple two-axis solar trackers, each…
Some regions frequently suffer from the devastating effects of earthquakes, as we have regrettably seen recently in both Ecuador and Japan. When it comes to AC drives, though, it’s not only seismic activity that they’re exposed to.…
38°C / 100°F – that’s the maximum daily temperature we had last summer here in Madrid for 24 consecutive days! However, that’s nothing compared to desert areas, where temperatures can – and do – exceed 50°C /…
The frequency converter for a solar-powered pumping installation is an essential component in order to achieve a reliable and performing system, with reduced installation and maintenance costs. There are a number of factors that should be considered when selecting…
