Abstract AR
في هذا البحث يتم إنشاء عاكس قنطرة كاملة بطريقة مقترحة.
هذا العاكس يتميز عن العاكس التقليدي بأنه ذو كفاءه عالية و مفاقيد أقل كما أن عملية إشعال مفاتيحه الإلكترونية تتم باستخدام المتحكمات الذكية.
و قد تم إضافة مفتاح إلكتروني (ترانزيستور) يوصل على التوالي مع قنطرة العاكس يعمل كمقطع تيار.
و يعمل هذا المفتاح الإلكتروني المقترح على إنشاء تتابع نبضي جيبي خلال فترة زمنية تساوي زمن الدورة الكاملة لتردد الحمل.
و يعمل المفتاح المقترح أيضا على الاستغناء عن دوائر الاخماد المعقدة و التي تستخدم مع الثايرستورز.
Abstract EN
In conventional pulse width modulated full bridge inverters; all power devices are switched at high frequency and are consequently subject to significant power losses.
In this paper, the bridge switches are controlled at the low frequency of the load voltage.
The proposed inverter is shown to have smaller device losses and higher power transfer efficiency than commonly used control schemes, while producing a lower harmonic distortion in the ac output voltage.
The proposed system is microcontroller-based trigger system which provides the pulse train to the IGBT buck converter switches and the main switches of the bridge inverter, the microcontroller is programmed to provide a sinusoidal pulse width modulated signal in a corresponding matter to the conventional system but it works at high efficiency, precision and with low components.
The proposed dual-stage system can eliminates the commutation circuit since when the IGBT buck is off the current through the main switch thyristors reduced to zero.
