No Late Submission Accepted; Early Submission is Welcome!
Problem 1
Neatly depict a DC/DC BUCK converter and analyze its operation in both CCM as well as DCM.
Neatly illustrate the following waveforms for both modes of operation: switch voltage, VQ, diode
voltage, Vd, inductor current, iL, diode current iD, input current, Iin, and inductor voltage, VL.
Problem 2
Consider a DC/DC boost converter, with the MOSFET switch being non-ideal, having a fixed voltage
drop of Von, during conduction. Derive the ratio between average input voltage and average
output voltage under such a non-ideal condition.
