Abstract

See full text

A Cockcroft-Walton (CW) switching voltage converter is disclosed. This CW switching converter includes a set of capacitors; an inductor coupled between an input voltage source and the set of capacitors; a set of switches; and an N-phase control module coupled to the set of switches. In some embodiments, each switch is controlled by the N-phase control module which is configured to sequentially and periodically effectuate a set of N voltage-conversion phases in a sequence of switching cycles. Note that each switching cycle effectuates a voltage conversion through the set of N voltage-conversion phases, wherein N is the conversion ratio of the CW switching voltage converter. Moreover, the N-phase control module is configured to effectuate a phase transition from a current phase to a subsequent phase when a zero-current switching (ZCS) condition on a given switch is met.
