AB - A large magnetic field ripple of the order of 10⁻² were observed at the first beam commissioning of J-PARC main ring in 2008, To eliminate the ripple, we had improved the magnet power supplies by reconstructing a trap-filter of 600 Hz and adopting an additional DCCT. We made differencial circuit and symmetrical wiring for all magnets. On the other hand, acceleration period was reduced from 2.5 s to 1.4 s for increasing the beam power with feedforward control. We summarize the improvements of the magnet power supplies in this paper.
