DC power supply for high power applications

摘要

A DC power supply (10) in accordance with the invention includes a plurality of DC to DC converters (20), each converter converting a multiple phase AC potential to a DC output potential (24) containing an undesired AC component; a circuit (30) for combining the DC output potential of each converter into a combined DC output potential (16) and arithmetically cancelling the undesired AC component; and a controller (22) for producing a time reference (A, B, . . . N) applied to each of the converters to set an angular relationship of each of the phases of each converter with respect to the applied time reference, the time reference of each of the converters being spaced apart from a time reference of another of the converters by an angle wherein ##EQU1## wherein n is equal to 2.sup.x where x is an integer and n is the number of converters.
