برمجة مبدل تردد ثلاثي الطور إلى أحادي الطور و تشغيله في الزمن الحقيقي

Abstract EN

Cycloconverters is used in driving induction and synchronous motors , at high power applications, like Cement mill drives, propulsion drive in ships and ore mills.

Usually, Phase controlled thyristor-bridges are used to drive it, because of its natural comutation between phases.

It is also, available for high operating voltages and currents,whitch makes it suitable for high power applications.

It converts the type of alternating power of the input with certain frequency, to an output power with a different frequency directly, and in a single stage.

In this paper, three phase to single phase cycloconverter was designed and implemented, using two anti-parallel three phases thyristor converters.

The triggering pulse generator was controlled in real time using data acquisition card (DAS) type (PCL1711), and (Matlab/Simulink).

Many tests were made for the performance of the cycloconverter, like changing the output frequency and voltage,and operating a single phase induction motor at alower speed.
