Budkers Institute of Nuclear physics builds booster for syncrotron light source NSLS-II. Booster should accelerate electrons from energy 200 MeV to energy 3 GeV, acceleration phase duration is 250 ms, repetition rate – up to 2 Hz. Booster magnet system includes 16 sextuples and 36 dipole correcting magnets powered separately. Forth-quadratant current sources for sextuples and correcting magnets have maximum output current ±6 А, maximum output voltage ±100 V, maximim output current ripples and long-term stability are better than 0,1% relative to 6 A. In ramping mode with current slew rate up to 200 A/s time lag between setpoint and output current is not more than 1msec and can be compensated by software. Results of power supplies system tests and commissioning will be presented in paper.

BINP SB RAS is developing various stepping motor drive devices for many years in accordance with requirements of acceleration and storage facilities. During this time several types of electric drives to control stepping motors with a 2-6 phases were developed. Electric drives are handled by special CANbus controller developed in BINP with smooth stepping motor acceleration and deceleration. Also special program was written to simplify adjustment of positioning system, this program allows operating using PC's Universal Serial Bus.
