Design of a singlle phase high current fully controlled rectifier

Design of a singlle phase high current fully controlled rectifier / Nur Adilah Nohamad Aseri
Penerus adalah salah satu penukar elektronik kuasa yang boleh mengubah voltan dari arus ulang alik ke voltan arus terus. Ia digunakan secara meluas dalam industri dan juga aplikasi domestik.Tetapi, kebanyakkan penerus di pasaran hanya mengeluarkan voltan keluaran yang tetap. Maka, aplikasi penerus adalah terhad untuk peralatan tertentu sahaja. Dalam projek ini, litar penerus perlu menghasilkan voltan purata boleh ubah dengan mengawal sudut fasa. Sumber Ac satu fasa 230 Vrms disambungkan kepada penerus gelombang penuh dengan menggunakan SCR berarus tinggi . Keluaran dikawal dengan melaraskan sudut fasa dari 0° ke180° bagi setiap SCR, menghasilkan voltan keluaran yang boleh ubah dari voltan masksima ke voltan manima dengan mengunakan mikropengawal (Arduino Uno). Dalam projek ini, voltan berjaya dikawal dari 0V kepada 205.5V. Arus purata maksima yang direkodkan ialah 0.934A, dikira sebagai arus tinggi sementara kuasa keluaran tertinggi ialah 191.937W. Sebagai kesimpulan, penerus fasa tunggal arus tinggi terkawal penuh berjaya direka menggunakan penerus jambatan penuh dan Arduino Uno. _______________________________________________________________________________________________________ Rectifier is the one of the power electronic converter that can modify from AC to DC. It widely used in industrial and also domestic application. But a lot of rectifiers in the market only produce fixed output so the applications of the rectifiers are limited for certain equipment only. In this project, the rectifier circuit should be able to produce a variable average voltage by controlling the phase angle. The single phase 230Vrms AC source is connected to full-wave rectifier by using high current thyristor. The output is controlled by adjusting the phase angle from 0° to 180° of each thyristors, resulting in an output voltage or output current which is variable from maximum to minimum voltage using Arduino Uno microcontroller. In this project, the voltage can successfully vary from 0V to 205.5V. The maximum average current used is 0.934A where it is considered as high current where the highest output power is 191.937W. As a conclusion, a single phase high current fully controlled had successfully designed by using a full bridge rectifier and Arduino Uno.
