	At the present stage of development of accelerating technology, it is important to create beam injection and extraction systems for newly created and modernized circular accelerators. Herewith, the high requirements associated with high energy of particles beams and a significant length of the channels are imposed both on the magnetic system of the transport channels and on power supplies. As part of development the NIKA (JINR) accelerator complex, the transport channel Buster-Nuclotron beam is creating in BINP. A powerful precision source with an output current up to 10 kA and an energy in the pulse up to 23 kJ is designed to power impulse dipole magnets and channel septum magnets. The presented article describes a pulsed source for magnetic lenses with a maximum output voltage up to 2 kV and a maximum output current up to 10 kA. The current amplitude instability from pulse to pulse is ensured at a level better than 10^-3. The stability of the amplitude of the magnetic field in the lenses can be improved to a value of 100 ppm by introducing additional feedback over the field of the magnet using the integrating ADC VsDC produced by BINP. The developed source meets both the requirements for stability of output parameters and automation requirements for integration into modern accelerator systems.

At the present stage of development of accelerating technology, it is important to create beam injection and extraction systems for newly created and modernized circular accelerators. Herewith, the high requirements associated with high energy of particles beams and a significant length of the channels are imposed both on the magnetic system of the transport channels and on power supplies. As part of development the NIKA (JINR) accelerator complex, the transport channel Buster-Nuclotron beam is creating in BINP. A powerful precision source with an output current up to 10 kA and an energy in the pulse up to 23 kJ is designed to power impulse dipole magnets and channel septum magnets. The presented article describes a pulsed source for magnetic lenses with a maximum output voltage up to 2 kV and a maximum output current up to 10 kA. The current amplitude instability from pulse to pulse is ensured at a level better than 10^-3. The stability of the amplitude of the magnetic field in the lenses can be improved to a value of 100 ppm by introducing additional feedback over the field of the magnet using the integrating ADC VsDC produced by BINP. The developed source meets both the requirements for stability of output parameters and automation requirements for integration into modern accelerator systems.

In process of development of accelerating technique, there is a question of automation of scientific complexes and the production accelerators more and more sharply. To increase in energy of a bunch there is body height of necessary accuracy of maintaining of parameters of the accelerator. All this imposes new requirements of the system of automation of an accelerating complex. In addition, for high energy power supplies, the question of safe operation was always particularly acute. It is necessary not only control loading parameters, for its maintaining in working order, but also to ensure safety at the current operation and service works. The submitted article contains the description of the controller for pulse power supplies. Distinctive feature of the controller, this combination in one device, several, the logically bound among themselves. Realization in the controller of the device of fast protection, allowed to realize a qualitative analysis of behavior of a power supply system on change of tension and a load current that is very important for definition of future possible problems and not nominal situations. Control is exercised on Ethernet network, also, perhaps and manual. As a core the digital alarm processor allowing to realize implementation of local scenarios of work maintaining of a part of independent functions is used.
