ABSTRACT:
Novel high frequency power distribution systems are disclosed. The system of the present invention uses a relatively high frequency AC (e.g. 100 kHz or higher) and distributes it by a high frequency bus which includes magnetic coupling. AC/DC converters are magnetically connected to the bus by way of associated magnetic coupling and rectify the AC to obtain DC power to be used by a respective load. The bus includes an inductive element which, in one embodiment, forms a series resonant circuit with a capacitive element of the AC/DC converter when it is magnetically connected to the bus.
