Power factor compensation and DC-link voltage regulation for a single-phase PWM multilevel rectifier Article uri icon

abstract

  • Active rectifiers are commonly used to address two issues in electric power delivery: DC voltage regulation and AC power factor improvement, through current tracking. In this study, the authors propose a non-linear controller that solves the DC voltage regulation and the AC current tracking for the single-phase active rectifier. The proposed controller is based on a partial input-output feedback linearisation and an adaptive indirect control of the zero dynamics. Numerical simulations are included to evaluate the performance of the proposed controller. © 2012 The Institution of Engineering and Technology.
