	High precision power supplies are used to power various accelerator magnets to generate stable magnetic field required for various dynamic functions of the charged particles in an Accelerator system. High current stability of the order of 5ppm to 100ppm depending on the various functional applications of the accelerator magnet is the main feature of these power supplies. The paper describes the various technical aspects and considerations depicting ripple reduction techniques, regulating loops, high precision temperature controller, R.F. pick-up attenuation, power dissipation control, handling of the input supply line power disturbances etc., which are important for achieving high stability of the power supply.
