Precision power supply system of the LEPTA group magnetic elements

An individual power supply source is usually used for each group of the identical magnetic elements in the accelerators of charged particles. We discuss the power supply and control system on the basis of additional current shunts applied for simultaneous supply of several groups of magnets in the positron storage ring LEPTA. Data on the use of the shunt of the linear and key converter are provided. The option of the device of a power supply system with transformation of the recuperated energy in the storage battery and supply from it of the precision power supply sources of the correcting magnets of LEPTA is considered. The channel of individual digital transformation of power supply system elements is given which allows one to build together with a reverse precision converter effective intellectual balanced power supply systems
