Abstract :
This work presents a single-phase current source converter topology that allows to mitigate typical DC-bus power ripple. Reduction of power ripple at twice of line frequency is one of the key elements to increase power converter density without lack of DC-bus stiffness. In this paper, low frequency ripple mitigation is achieved by adding a third leg connected to the output filter central point. Details of control strategy and modulation are presented. Simulation results are provided to validate the theoretical analysis.
