摘要： An electric power system is provided that includes a three-phase to ten-phase step-up transformer. The transformer includes primary winding groupings, secondary windings, and third windings. The primary winding groupings include sub windings. Primary winding groupings are coupled to form a delta configuration and coupled to secondary windings and third windings, which may also be coupled to each other. The outputs at second ends of secondary windings and third windings are greater than the outputs at the second ends of primary windings. Diode pairs are connected to each other, each diode pair having an inner connection connected to one of the outputs of the transformer and first and second ends respectively connected to a positive dc bus and a negative dc bus. An inverter is connected to the d busses. The diode pairs operatively rectify the transformer output voltage to form a DC voltage with a reduced common mode voltage.

摘要： 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.

摘要： A multi-phase autotransformer (10) is disclosed. The exemplary transformer includes primary windings PWA, PWB, PWC) and secondary windings (SWA1-SWA4, SWB1-SWB4, SWC1-SWC4). The primary windings are connected in a delta configuration and to a three-phase input voltage source. Each secondary winding is electrically connected to a primary winding but is magnetically coupled to a different primary winding. Three sets of secondary windings provide three three-phase outputs (350A, 350B, 350C), each of which has a voltage which is less than the three-phase input voltage, the three-phase output of each set being phase-shifted with respect to the other sets. These three sets also, collectively, provide a multi-phase output (325). Another set of secondary windings, in conjunction with the input voltage, provides another multi-phase phase output (360) which has approximately the same voltage as the three-phase input voltage.
