摘要：

This paper presents a control strategy for pulsewidth-modulation rectifiers without grid voltage sensors employing a current-shaping strategy. The proposed technique has the ability to reject harmonic components from grid voltage and power factor adaptation in the presence of uncertain grid impedance. The harmonic compensation is selective, obtained from multiple resonant modes tuned in the desired frequencies. The resulting control laws obtained by the proposed method can be easily implemented on digital processors. Aspects of robustness and performance are regarded in the control synthesis with an optimum approach for a satisfactory operation. A prototype of 1.1 kVA was implemented for experimental verification and validation.
