Abstract    This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nature of the Vienna configuration, balancing the output capacitors voltages is inevitable leading to a modified virtual flux based technique. Applying this modification, a separate switching table has been jammed into the proposed technique in order to control the capacitors voltages. Simulation results show the superiority of the virtual flux technique over the conventional Vienna control techniques from point of the mentioned advantages.

چکیده    در این مقاله، کنترل مستقیم توان بر مبنای شار مجازی برای یکسوساز وی‌ینا پیشنهاد گردیده است. عدم نیاز به سنسورهای ولتاژ ورودی، عدم نیاز به حلقه تنظیم جریان و بلوک مدولاسیون پهنای پالس ولتاژ به همراه مجزا سازی توانهای اکتیو و راکتیو، برخی از مزایای برجسته این روش هستند که آن را برای کنترل یکسوسازهای اکتیو متعارف مناسب ساخته‌اند. با این حال، به دلیل ماهیت سه سطحی ساختار وی‌ینا، متعادل سازی ولتاژ خازنهای خروجی امری اجتناب ناپذیر است و منجر به پیشنهاد تکنیک تغییر یافته‌ای بر مینای شار مجازی در این مقاله گشته است. با اعمال تغییرات مذکور، یک جدول کلیدزنی مجزا جهت کنترل ولتاژ خازنها در داخل تکنیک مذکور گنجانده شده است. نتایج شبیه سازی برتری روش پیشنهادی شار مجازی را از نقطه نظر مزایای ذکر شده نسبت به سایر تکنیکهای کنترلی وی‌ینا نشان می‌دهد.
