In this paper, the method of reducing harmonics and correcting of power factor in single PWM converter associated with diode rectifier and boos converter is studied<br/> 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 switching power loss and easy configuration 0 control circuit are obtained by adopting discontin -uous 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.
