About this person
His other important invention was the constant voltage AC electrical generator in the Ganz Works in 1883. The missing link of a full Voltage sensitive - voltage intensive (VSVI) system was the reliable AC Constant Voltage generator. Therefore, the invention of the constant voltage generator at the Ganz Works played a crucial role in the beginnings of the industrial scale AC power generating, because only these types of generators can produce a stated output voltage, regardless of the value of the actual load.
