Abstract
Current source converters and control methods are presented for high dynamic performance by implementing a DC link current control loop parallel to one or more motor control loops, with a DC link current control command value for operating the current source rectifier being derived at least partially independent of the motor control command values, wherein certain implementations drive the current source rectifier to its maximum rated value, or the DC current command value can be set above an amount required by the current source inverter using a gain factor which can be fixed or can itself be adjusted based on one or more motor control error values for balancing as-needed dynamic performance and efficiency.
