The invention relates to a sequential multiplication current-type pulse power supply for electromagnetic emission, which belongs to the technical field of electromagnetic emission. The multiplication current-type pulse power supply comprises a pulse capacitor, a first switch, a load, a first diode, and n cascaded switch groups, wherein the positive pole of the pulse capacitor is connected with the anode of the first switch so as to form series connection with the first switch, and the negative pole thereof is connected with the anode of the first diode; the cathode of the first switch is connected with the cathode of the first diode so as to enable the pulse capacitor to form parallel connection with the first diode after being serially connected with the first switch; the cathode of the first diode is connected with the current inflow ends of the n cascaded switch groups, the current outflow ends of the n cascaded switch groups are connected in parallel and then connected with the current inflow end of the load, and the grounding ends are connected in parallel and then connected with the grounding end of the load. According to the pulse power supply disclosed by the invention, the waste energy of a system does not need to be directly consumed on a muzzle quenching arc in the form of heat energy, thus reducing the loss of the system, increasing the efficiency of the system, shortening the emission period of the whole system, and providing an effective way for realizing short-time multiple objects of the system.
