1. A Cockcroft-Walton (CW) switching voltage converter, comprising:
a set of capacitors;
at least one inductor coupled between an input voltage source and the set of capacitors; and
a set of switches, wherein each switch in the set of switches is controlled by a split-phase control module which is configured to sequentially and periodically effectuate a set of N voltage-conversion phases in a sequence of switching cycles, wherein each switching cycle in the sequence of switching cycles effectuates a voltage conversion through the set of N voltage-conversion phases, and wherein N is the conversion ratio of the CW switching voltage converter;
wherein the set of N voltage-conversion phases is divided into a first major phase and a second major phase which are associated a first and a second complex configurations of the set of switches, respectively, wherein the first major phase is further divided into a first set of sub-phases which is composed of a first sub-phase having the first complex configuration and one or more additional sub-phases corresponding to one or more sub-configurations of the first complex configuration, and wherein the second major phase is further divided into a second set of sub-phases which is composed of a second sub-phase having the second complex configuration and one or more additional sub-phases corresponding to one or more sub-configurations of the second complex configuration.
