The injection bump power supply of J-PARC 3GeV RCS is composed of the assemblies that are multiple connection with IGBT choppers, and It can make optionally current wave form. But the high-frequency noise due to the switching of the IGBT choppers has caused the damages to the control system and the monitor system. So the ground wires that connect to each power supply panel and each magnet has been changed to copper sheets. As a result, the noise decreases rapidly and it kept balance controllable.
