This disclosure describes systems, methods, and apparatus for a pulsed power supply assembly that distributes pulsed power to two or more loads using a single pulsed power supply. A pulsed power supply of the assembly can phase shift pulses to the different loads to ensure that there is no overlap between pulses at the outputs even where target frequencies and/or duty cycles for the different loads would otherwise call for such pulse overlaps. Variances applied by the pulsed power supply can be limited by attempts to keep average parameters of the pulse trains provided to the different loads to within predetermined variances.
