Digital Power Suppliers

The modernization project of the low-current power supply system of Kurchatov Synchrotron Radiation Source has been designed and is implemented. It includes transition to the new power suppliers to feed electron beam orbit correctors and focusing lenses. Marathon Ltd company has developed a set of unipolar and bipolar digital power supplies with rated current from 6 to 40 amps. The power sources current control resolution is 0.01% of Imax and current stability 10-4 of Imax. The power suppliers are controlled via CAN bus with CANopen protocol.

Keywords: digital power supply, direct digital control, CANopen protocol.
