The inherent second-harmonic ripple power in a cascaded H-bridge (CHB)-based motor drive system poses the demand of large capacitors in the dc link of each cell. In this paper, an active power decoupling method based on negative sequence current injection and its corresponding dual voltage closed-lo...
