The embodiment of the invention provides a control device and a control method for a switching pulsed power supply. The switching pulsed power supply consists of a plurality of switching pulsed power supply units connected in parallel. The control device comprises a main control panel, PI regulators and current sampling devices, wherein the main control panel is used for synchronously outputting pulse control signals with the same duty cycle to a driver of a full-bridge converter for each switching pulsed power supply unit and setting the given current value; the PI regulators and the current sampling devices are independently arranged for the switching pulsed power supply unit; each current sampling device is used for acquiring the actual current output value of the switching pulsed power supply unit corresponding to the current sampling device and feeding the actual current output value back to the PI regulator corresponding to the switching pulsed power supply unit; the PI regulators compare the actual cur
