Abstract
A method and apparatus for transferring power to a load. An AC-to-DC converter output for an AC-to-DC converter is connected to a filter circuit input in a DC-to-DC converter via a connector such that a no-break power transfer occurs when transferring between providing power for the load by the AC-to-DC converter and providing power for the load by the DC-to-DC converter. The topology of the AC-to-DC converter needs only 21 windings for achieving a 24-pulse transformer rectifier unit.
