1. A high power electrical distribution system for distribution of high power to a plurality of consumers arranged on a rotatable element, said distribution system comprising:
at least one high frequency alternating current (HFAC) generator configured to generate HFAC having an AC frequency of at least 10 kHz, a rotary power transformer connected to said at least one HFAC generator, wherein said rotary power transformer includes a stationary part and a rotatable part, and is configured to receive HFAC from said at least one HFAC generator, and to couple HFAC electrical energy from said stationary part to said rotatable part, at least one high power distribution bus located on said rotatable element, and configured to receive HFAC from said rotary power transformer and to distribute HFAC to said plurality of consumers, and a plurality of power converters arranged on said rotatable element, wherein each power converter is configured to receive HFAC from said at least one high power distribution bus, to supply a subset of the plurality of consumers, and to convert said received HFAC to an electrical power form suitable for the subset of consumers that the power converter supplies, wherein each power converter comprises a transformer unit or a transformer/rectifier unit configured to supply transformed AC or DC to the subset of consumers, wherein said rotatable element is a rotating radar antenna of a phased-array radar system, wherein said rotatable element includes more than 100 separate consumers, and wherein the rotary power transformer is configured to provide an HFAC output of at least 1 kW to said at least one high power distribution bus. |
