A STUDY OF OPERATING MODES FOR COMPULSATOR BASED EM LAUNCHER SYSTEMS

The compensated pulsed alternator (compulsator) is a versatile power s upply capable of interfacing with the electromagnetic launcher in vari ous ways, The method that has been explored at length with several sys tems is the single phase option, Several variants of this option, some using advanced pulse shaping techniques, have been discussed in prior publications. Besides this basic single pulse method of operating the re are several other methods each with its pros and cons, The multipha se option is discussed in this paper. Within the broad class of multi- phase systems there are further sub-classes, namely alternating curren t drive and unidirectional current drives, Thus the branching of these operating modes gives rise to a variety of operating modes, Each one of these operating modes is described and simulation results are prese nted.
