Patent ID: 8125808

Claim:
A three-phase bridge rectifier circuit connectable to at least one AC voltage source via a plurality of input lines and to a load via a pair of output lines, said at least one AC voltage source configured to supply said three-phase bridge rectifier circuit with a plurality of AC voltage waveforms that differ in phase by a certain amount, said three-phase bridge rectifier circuit comprising: a first and second field effect transistor, a source-drain path of said first field effect transistor connected in series with a source-drain path of said second field effect transistor to form a first series transistor combination connected across said pair of output lines; a third and fourth field effect transistor, a source-drain path of said third field effect transistor connected in series with a source-drain path of said fourth field effect transistor to form a second series transistor combination connected across said pair of output lines; a fifth and sixth field effect transistor, a source-drain path of said fifth field effect transistor connected in series with a source-drain path of said sixth field effect transistor to form a third series transistor combination connected across said pair of output lines; and a plurality of diodes, each connected between a drain of one of said field effect transistors and a gate of a different one of said field effect transistors.
