Method of operating an electrical device

摘要

The method involves attaching transformers (60, 70) to clocked converters. The converters are provided with same clock frequencies and are phased differently for operating the converters relative to each other. Phase of the converters is adjusted such that phase difference between converters is less than marginal phase, where the marginal phase is calculated based on number of converters attached at the transformers. An independent claim is also included for an electrical arrangement with two transformers.
