The controllers communicate via a dual-redundant Ethernet network. of Electrical and Computer Engineering University of Illinois at Urbana-Champaign overbye@illinois. In the end, Tesla was forced to invent, develop, and apply, isochronous generator technology in order to produce frequency stable sine waves. One isochronous controller is attached to each generator, the inverter, and the static switch. This is done by adjusting the speed of the generator in response to changes in the load demand.
