Abstract
Systems and methods for improving the current pulse from multiple pairs of pulsed alternators used for driving large loads such as an electromagnetic launcher (i.e., “rail gun”) load. Conventional current pulse ripples are reduced by interleaving pulses from multiple pairs of contra-rotating pulsed alternators. Current pulses supplied by different pairs of pulsed alternators are timed so that they are interspersed between one another to provide more pulses for a given launch time. The interleaved current pulses increase the frequency and reduce the magnitude of the ripple on the average load current.
