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 had 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. ZBD was an abbreviation of the three men's names: Zipernowsky, Bláthy and Déri. Déri is also noted for inventing the single phase type of repulsion motor
