The harmonic currents generated by the single-phase rectifier are well known. As the levels of these currents become larger, the use of power conditioners such as shunt active filters to lower the levels is becoming more attractive. In order to analyze the interaction between the condition, ac system, and rectifier it is necessary to have an accurate model of the rectifier. This paper describes a frequency-domain analytical model of the single-phase rectifier. The model includes the dominant frequency transfer mechanisms. These are the direct transfer and that due to the modulation of the switching instants. A small-signal linearized analysis is presented and the behavior predicted is confirmed by perturbation analysis using time-domain simulation. Accurate results are obtained, and the importance of including the switching instant modulation is shown.
