Question 3 / Soalan 3 The circuit in Figure Q3 works in continuous conduction mode with the following values:

D=0.25,V_(d)=6V,L=37.5\mu H,I_(0)=1.5A

and

I_(8)=100kHz

. Assuming that the capacitance value is large, Litar pada Rajah Q3 beroperasi pada mod pengaliran berterusan dengan nilai-nilai parameter seperti berikut:

D=0.25,V_(d)=6V,L=37.5\mu H,I_(0)=1.5A

and

f_(x)=100

kHz . Dengan anggapan bahawa nilai kemuatan adalah tinggi, (a) What type of circuit is this? State the ratio between output voltage and input voltage. Apakah jenis litar ini? Nyatakan nisbah antara voltan keluaran dan voltan masukan. (5 marks/5 markah) (b) Give two other types of DC-DC converters and state the ratio between the output voltage and the input voltage for each of them. Berikan dua jenis lagi penukar AT-AT dan nyatakan nisbah antara voltan keluaran dan voltan masukan bagi setiap jenis penukar. (c) Calculate the output voltage Kirakan voitan keiuaran. (8 marks/8 markah) (d) Sketch the inductor voltage waveform. Indicate all values at corresponding time. Lakarkan bentuk geiombang bagi voltan pengaruh. Tunjukkan semua nilai pada masa sepadan (26 marks/26 markah) (e) Sketch the inductor current waveform. Indicate all values at corresponding time- Lakarkan bentuk geiombang bagi arus pengaruh. Tunjukkan semua nilai pada masa sepadan. (33 marks/33 markah) (f) If the converter operates at the boundary between continuous and discontinuous mode, state the relationship between the average output current and the peak inductor current. Sekiranya penukar ini beroperasi pada mod pengaliran antara sempadan berterusan dan tidak berterusan, nyatakan hubungan antara arus keluaran purata dan arus pengaruh puncak.help
