Abstract:
A three-phase bridge rectifier circuit (BRC) connectable to an AC voltage source (ACVS) via input lines (151, 153, 155) and a load (109) via output lines (157, 159). ACVS (102, 104, 106) supplies BRC (100) with AC voltage waveforms that differ in phase. The BRC includes a three-phase bridge rectifier circuit comprised of field effect transistors (FET) and gate drive circuits (GDC). Each GDC (101a, 103a, 101b, 103b, 101c, 103c) supplies a voltage to a gate of a respective FET (110, 112, 114, 116, 118, 120) for switching the FET to its “on” state at a certain time. The BRC further includes a diode (190, 128, 198, 148, 113, 168) connected between a drain of each FET and a terminal of each GDC. The BRC can further include voltage divider circuits (192/188, 130/140, 107/196, 150/160, 115/111, 170/180) and/or voltage clamping devices (121, 131, 123, 133, 125, 135).
