Abstract |
In this paper, the method of reducing harmonics and correcting of power factor in single PWM converter associated with diode rectifier and boost converter is studied. In the general diode rectifier there are some problems that discontinuous current of reducing power factor and including distortion of harmonics at the input current affects other sources. To solve the problems of performance degradation due to pulse waveform in the input current, the ac-dc converter in which the harmonic distortion in the input current is reduced using a third-harmonic-injected PWM is proposed. A lower power loss of switching and easy configuration of circuit are obtained by adopting discontinuous current mode. Simulation and experimental results of ac-dc converter with 5[kHz] switching frequency are presented and correction of power factor and reduction of total harmonic distortion was established. |
