Description
Summary:The specifications and schemes of the main components of the power supplies of the unbalance currents of focusing and defocusing magnets with a series feeding scheme of a nuclotron are presented and the devices are described. The devices were made on the basis of thyristor rectifiers. High operating speed, small ripples, and low noise of the output current are achieved through the use of transistor blocks for the current regulation in a linear mode. The special feature of the described power supplies is the operation of the thyristor rectifiers in the so-called tracking mode that allows to minimise the power losses on the pass transistor bank and to regenerate the energy stored in the inductive elements to the AC network. An additional feedback loop is applied for precision current regulation.
