Abstract:
A series-parallel alternator-rectifier system, with multiple parallel rectification paths, the series-parallel alternator-rectifier system comprising:an AC power supply comprising at least a first set of windings and a second set of windings arranged such that in-phase alternating voltages are respectively generated therein;a positive DC bus and a negative DC bus;a rectifier apparatus coupled to said AC power supply including series parallel switches and at least a first main leg and a second main leg interconnected in a parallel circuit relationship, each main leg comprising a first rectifier, a second rectifier, a third rectifier, and a fourth rectifier with a connection in series from said negative DC bus to said positive DC bus and oriented so as to conduct current from said negative DC bus to said positive DC bus;a first bypass leg, comprising a first rectifier and a second rectifier with a connection in series from said negative DC bus to said positive DC bus and oriented so as to conduct current from said negative DC bus to said positive DC bus;wherein said rectifier apparatus is coupled to said AC power supply such that said first set of windings includes a connection between a point between said first rectifier and said second rectifier of said first main leg and a point between said first rectifier and said second rectifier of said second main leg, said second winding includes a connection between a point between said third rectifier and said fourth rectifier of said first main leg and a point between said third rectifier and said fourth rectifier of said second main leg; anda junction of said first rectifier and said second rectifier of said first bypass leg includes a connection to a junction of said second rectifier and said third rectifier of said first main leg.
