Abstract

This paper proposes a pulsed power supply scheme to generate highly stabilized high magnetic fields (ripple less than 10 ppm), which are needed for some kinds of scientific experiments (such as the nuclear magnetic resonance experiment). The power supply presented in this paper consists of a large-capacity pulse-forming network (PFN) power supply and a small-capacity power electronics power supply (PEPS). The PFN provides a background field, and the PEPS compensates for the flattop of the background field to get a highly stabilized magnetic field.
