A method of controlling a power converter ( 258 ) of a synchronous machine drive system ( 100 ) determines position and speed of a rotor ( 350 ) of the synchronous machine ( 300 ); regulates a current vector relative to a reference frame, having a direct-axis component and a quadrature-axis component, the regulating step selectively causing the current vector to lag a quadrature axis of the machine ( 300 ); and outputs a command signal to the power converter ( 258 ) as a function of the regulating step. According to one implementation, this process creates higher total torque and maintains supply voltage within a maximum level during a high speed range of the machine. |
