Herkese iyi forumlar. Bitirme projemde AC-DC konventör yapacağım. Fikirlerinizi almak istedim. Projede benden istenen AC giriş ve ayarlanabilir DC çıkış. 0-5-10-15 volt çıkışlarını 4 ayrı tristör ile ardunio kullanılarak çıkış yapmasını isteniyor. 10V çıkışının 5W güç üretilmesi isteniyor. Tüm sistemin verimliliği minimum %70 olması isteniyor. Ben devreyi PROTEUS üzerinden çalışıp ardunio üzerinden proglayacam. Nasıl bir yol izleyebilirim hangi parçaları ve entegreleri kullanarak bunu tasarlayabilirim?

Title: Thyristor based Full-Bridge AC-DC Converter with Arduino
Overview of the project
AC-DC conversion or rectification is a crucial step in many applications such as renewable energy systems, electrical vehicles, energy storage systems, and etc. In this project, a variable DC voltage will be produced from a fixed single-phase AC source with a thyristor based full-bridge AC-DC converter. The advantage of this design over classical diode-based rectifiers is that the output DC voltage can be varied or controlled. The converter that is planned to be designed will consist of 4 thyristors. The firing signals of the thyristors will be generated by a compatible version of Arduino. By this way, the output DC voltage of the converter can be varied. To change the firing angle in real-time, a potentiometer or any suitable method can be used in the design. To decrease the input voltage of the converter, a step-down transformer can be used at the input of the design. The reduce ripple factor, a capacitor or any suitable filtering can be used at the output.
