MFCG as Future Military PPS

As a kind of mobile pulsed power supply (PPS), the magnetic flux compression generator (MFCG) can be used in many military fields, but the MFCG concept has not been explored systematically. The definitions of MFCG were given in two ways: the electric circuit model and the magnetic field model, and the latter was indispensable to resolve many technical difficulties. According to the field model, the working principles of the MFCG with perfect solenoid were shown as the magnetic flux conservation or the magnetic flux linkage conservation. The inherent coherence of the two definitions was also outlined. The names of MFCGs were discussed, and the distinguishing features of MFCG from other pulsed generators were summarized. According to the different forms of the windings and the different moving modes of the armatures, 14 kinds of MFCGs were classified systematically, and their characteristics were generalized respectively. The most useful kinds of MFCGs were the piston type, the explosive one, and the rotary one. Their technical aspects were reviewed. The key technology of the piston type MFCG was analyzed and the conclusion is that the conical armature without any longitudinal slits on its surface is necessary. The working process of the two stages explosive MFCG for the microwave bomb was analyzed: the first stage as a magnetic energy accumulator, and the second as a pulsed generator. The CPA, as a kind of rotary MFCG, was developed as a kind of drum alternator in the big ship to power the EM launcher. All those essential work was important for MFCG concept, theory research, technology development, and military applications.
