VSCF STARTER/GENERATOR SYSTEMS |
摘要 |
A variable speed, constant frequency starter generator system is provided with a dynamoelectric machine, electrically connected to a multiple-phase bus and pair of multiple-phase rectifiers for producing a DC voltage on a pair of link conductors. An inverter converts the DC voltage to floating AC voltage which is further converted to a ground-referenced AC voltage by a transformer. During generator operation, the output voltage of the machine is rectified by at least one of the rectifiers to produce a DC voltage on the link conductors which is converted to a constant frequency AC voltage by the inverter. During starter operation, an externally supplied AC voltage is applied to the transformer. The transformer converts the externally applied AC voltage to a pair of phase-displaced AC voltages which are rectified by rectifiers to produce twelve-pulse rectified DC voltage on the link conductors. This reduces the harmonic content of the current supplied by the external power source.
