  The injection bump system of the synchrotron of the Wuwei Heavy-ion Medical Machine(WHMM) consists of four horizontal bump magnets to merge the injection beam with the circulating beam. In order to control the injection beam with sufficient accuracy, the bump mag-nets need four pulsed power supplies with high speed, precision, reliability. The power supplies, whose IBGT (Insulated Gate Bipolar Transistor) are working in the linear area, are required to output the maximum current of 2900A. Furthermore, the current pulse is activated by synchronous triggering events, the current pulse frequen-cy is required about 30Hz, and that the pulse current falling edge should be less than 60us. In this paper, a control system for the pulsed power supplies was described in details. The commissioning results showed that the control system owned high reliability and flexible and that beam could be injected effectively into the synchrotron of the WHMM. In addition, one on-line current pulse waveform is shown in the result section.
