The circuit below shows a DC-DC converter. Assume that the
inverter operates in continuous line mode (CCM), ie the
coil/inductor current has no zero crossing:
a. Draw the two schematic circuit diagrams for the inverter: (i)
when the switch "S" is ON and (ii) when the switch "S" is OFF.
b. Qualitatively sketches the steady-state waveforms of the coil
voltage and coil current for one switching period (for input
voltage Vd, output voltage Vo, operating cycle D, on-interval for
switching tone and switching period Tsw).
c. Derive an expression for the relationship between output and
input voltage (Vo / Vd) which is expressed with the duty cycle D to
the switch.
d. Which of the typical DC converter topologies (buck, boost or
buck-boost) has the same operating principle as the converter shown
above?
