摘要：A power conversion array delivers power to a load. The array includes at leastfour power converters, each of the power converters comprising an output power portfor connection to the load and a synchronization port for passing synchronizationinformation. A synchronization medium connected to the synchronization ports of the
converters carries the synchronization information among the converters. The
synchronization medium defines paths among the synchronization ports such that everysynchronization port is connected to every other synchronization port by at least onepath that does not include a connection to the synchronization port of any of the otherconverters. In another aspect, in arrays which include at least three power converters, thesynchronizing medium conveys synchronizing information via impedance elementsconnected to the synchronization ports by coupling conductors, and the path betweenany pair of coupling conductors includes exactly two impedance elements. In anotheraspect, an integral assembly includes impedance devices, each of which is formed by anelement that is specific to that device and a common element that is shared by thedevices, and a mechanism (e.g., insulation) that prevents exposure of the commonelement to the environment.
