Analysis of the TFTR toroidal field power supply and its interactions with other loads
The rectifiers which supply the four major pulsed loads of the Tokamak Fusion Test Reactor (TFTR) share two flywheel generators. Thus there is a possibility of significant interaction between these rectifiers by way of the notched voltage waveforms which they create at the generator terminals. The way the notched waveforms arise is explained and an analysis is presented of the buildup of current in the toroidal field (TF) coil, which is the largest load. From this analysis, the notched waveform caused by the TF rectifier is derived and its effect on the other rectifiers is investigated. It is concluded that with the present conceptual design parameters, the external effects of the interactions are likely to be small. However, the internal control circuits of the rectifiers must be carefully designed to minimize those effects. In case interactions prove to be more significant than anticipated, balancing reactors and shunting capacitors in the ac lines are considered as possible remedial measures.
