TWELVE PULSE LOAD COMMUTATED INVERTER DRIVE SYSTEM Abstract of the Disclosure A control system for powering an AC load such as a polyphase synchronous motor having at least two sets of three phase (3) windings. Each three phase winding set is powered by an independently operable six pulse load commutated inverter drive including a source side converter and a load side converter coupled together by means of a DC link and wherein the source side converter and the load side converter are operated in accordance with respective current and load angle regulators which respond to torque command signals generated by speed regulators. The two motor drives operate concurrently in separate control channels which are substantially independent of one another with the exception that in one embodiment, which is the preferred embodiment, the speed regulator and the motor terminal overvoltage regulator are cross-coupled to effect a balanced torque command and motor terminal voltage from each channel while still providing for continued motor operation by one of the motor drive channels in the event that the other becomes inoperative for any reason. In a second embodiment, one of two redundant speed regula- tors is adapted to provide a common torque command to both channels with the other speed regulator taking over in the event of the failure of said one speed regulator.
