How the Early 1980s Micro- and Power-Electronics Innovation in Germany Revolutionised Wind Energy Systems

It was in 1980 when I first came in touch with a completely new field in systems and control engineering: using micro-electronics for control, integrated circuits, which at that time had recently developed into the first 4 bit and soon 8 bit, the so-called microprocessors. Up to then, digital signal processing and control used to be a field for expensive mainframe and mini-computers, controlling large installations for processing, manufacturing and production installations or military, air and space equipment.
