Draw the circuit diagram of a DC to DC converter – (forward
converter, step-down or buck converter). Describe its principle of
operation. Draw the waveforms of: voltage across the diode, current
through the diode, current through the transistor and current through
the inductor. Write the expression and diagram for transfer function.
