ABSTRACT:
An n-phase transistor active bridge circuit (BC) connectable between at least two input lines (103, 105, 1051, 1053, 1055) and a pair of output lines (134, 136, 1057, 1059). The BC comprises a plurality of field-effect transistors (FETs) of the same channel type. The FETs (102, 104, 106, 108, 1010, 1012, 1014, 1016, 1018, 1020) are connected to convert an n-phase AC waveform (402, 1102, 1104, 1006) to a DC waveform (502, 1302). The n-phase AC waveform is applied to BC by a voltage source (101, 1002, 1004, 1006) coupled to the input lines. Gate drive circuits (170, 172, 174, 176, 1001a,1001b,1001c,1003a,1003b,1003c) supply a voltage to gates (139, 143, 147, 151, 1024, 1034, 1044, 1054, 1064, 1074) of the FETs for switching the FETs to their “on” states or “off” states at predetermined times.
