Due to the enhancement in high-speed switching semi conductor devices, the employ of threephase PWM boost rectifier (BR) has grown to be more common in the past decade. The PWM rectifier can provide input currents without distor ti n and with unity power factor at the supply terminals. The description and modeling of the thre e-phase PWM rectifier have been analyzed using the voltage source inverter (VSI) with resist ive load. The proposed control scheme in this paper has two closed loops to compute the three-pha se reference currents of PWM rectifier. The first, namely dc load current loop, and the second, using dc bus voltage loop. The unity power factor and reduction of pollution harmonic is compl ete y fulfilled with current controller that is applied linear current controller. The Simulation a d experimental results verify the operational characteristics of the PWM rectifier. دا يدزا باب سأ ن م ق لغلاو حت فلا ةعيرس لا ت صوملا هاب شأ ن م ة ينورتكل ا حيتا فملا ةعان ص ىف لئاھلا مدقتلا ربتعي ىف ةرثكب دھجلا ززعم دحوم مادختسا ةريخ.ا ةنو/ا . د ھجلا زز عم د حوم مدختس ي لكاش م ن م د حلل را يت تا يقفاوتلا تقولا سفن ىفو ىلع لمعي ةردقلا لماعم نيسحت ردصملا دنع . مادختساب دھجلا ززعم دحومل جذومن لمعو فصو مت لدبم لمحك ةمواقم مادختسا عم ردصملا دھج . حلل دھجلا ززعم دحومل مكحت نيراسم ثحبلا اذھ ىف حرتقا ىلع لوص ردص ملل ة يعجرملا تارا يتلا : ف ثكملا د ھج مادخت ساب ىنا ثلا راس ملاو رمتس ملا ل محلا را يت مادخت ساب لو.ا راس ملا رمتسملا . زز عم د حومل ة ينورتكل ا حيتا فملا ق لغو حت ف تاض بن ىلع لوصحلل ىطخلا رايتلا مكحت ةقيرط تمدختسا ل ماعم نيسحتو تايقفاوتلا ليلقت ةيلمع مامت> دھجلا ةرد قلا . جئا تنلا تح ضوأو ة يلمعلاو ة يرظنلا ةرد ق زز عم د حوم دھجلا اعم نم نسحي تقولا سفن ىفو تايقفاوتلا ليلقت ىلع م ةردقلا ل ردصملا دنع .
