| Summary, etc. | Selective harmonic elimination PWM (SHEPWM) technique is used with cascaded <br/>multilevel inverter connected to DC sources for eliminating specific harmonics existed <br/>in the output voltage while reducing switching losses to minimum. Applying SHEPWM <br/>technique requires solving transcendental equations to determine switching angles <br/>needed for this harmonic elimination process corresponding to voltages of DC sources <br/>which necessitates high computational processes that is beyond the capability of <br/>contemporary computer algebra. The problem arises when voltage of any DC sources <br/>changed the equations have to be resolved fast enough for updating the switching angles <br/>to avoid the loss of the harmonic elimination process for several fundamental cycles. The <br/>approach proposed in this thesis is composed of using well-trained ANN as a regression <br/>tool to generate accurate new values for the switching angles instantly whenever voltage <br/>of any DC sources changed and run this ANN on FPGA platform for faster execution <br/>time at low-cost |

| Summary, etc. | يستخدم نظام تغيير عرض النبضة المبني على التخلص الانتقائي للتوافقيات مع مناوبات التيار متعددة المستويات المتتالية والمغذاة من مصادر تيار مستمرللتخلص من توافقيات بعينها موجودة في جهد الخرجبينما يتم تقليل الفقد في القدرة أثناء الفصل والتوصيل إلى الحد الأدنى. يحتاج تطبيق هذا الأسلوب إلى حل معادلات متسامية لإيجاد زوايا الفصل والتوصيل المطلوبة لعملية الإزالة التوافقية تلك والمناسبة لجهود مصادر التيار المستمر مما يتطلب قدرة حسابية عالية تفوق قدرة المعالجات الحالية.وتنشأ المشكلة عندما يتغير جهد أي من مصادر التيار المستمرإذ يجب إعادة حل المعادلات بسرعة كافية لتحديث زوايا الفصل والتوصيل لتجنب فقدان عملية الإزالة التوافقية لعدة دورات أساسية.النهج المقترح في هذه الرسالة يتألف مناستخدام شبكة عصبية صناعية مدربة جيداكأداة انحدار لتوليد قيم جديدة ودقيفةلزوايا الفصل والتوصيل فورا عندما يتغير جهد أي من مصادر التيار المستمر ويتم تشغيل هذه الشبكة على منصة مصفوفة البوابات المنطقية القابلة للبرمجةللحصول على سرعة تنفيذ عاليةبتكلفة منخفضة. |
