Abstract
Systems and methods disclosed herein include a controller for a current source rectifier that is configured to facilitate operation in both continuous and discontinuous conduction modes. The controller comprises a discontinuous mode detection unit configured to determine when input current of the current source rectifier becomes discontinuous and a duty cycle calculation unit adapted to calculate duty cycles for the current source rectifier differently for operation in continuous or discontinuous mode. The controller is adapted to transition to a mode of operation to provide an input current that approximates a sinusoidal current during both the continuous and discontinuous modes of operation. The controller outputs control signals to turn on one or more of the electrical switches in the current source rectifier based on the calculated duty cycles.
