a buck converter with the following parameters: Vin= 50V, D=0.4, L=270μH, C=1μF, f=25kHz, R=20Ω
a) Draw the waveform of the output voltage, Inductor current, the
voltage on the diode and MOSFET. Measure the ripple in the output
voltage and Inductor current.
b) Increase the switching frequency (choose any three different
values) while keeping other parameters fixed (Vin= 50V, D=0.4,
L=270μH, C=1μF, R=20Ω) Draw the waveform of the output voltage and
Inductor current. Measure the ripple in the output voltage and
Inductor current.
c) Increase the inductor size (any three different values) while
keeping other parameters fixed (Vin= 50V, D=0.4, C=1μF, f=25kHz,
R=20Ω) Draw the waveform of the Inductor current. Measure the
ripple in the Inductor current. Comment on the results.
d) Increase the Capacitor size (any three different values) while
keeping other parameters fixed (Vin= 50V, D=0.4, L=270μH, f=25kHz,
R=20Ω) Draw the waveform of the output voltage. Measure the ripple
in the output voltage.
