1. Buck-Boost converter simulation
a) Use an ideal switch and ideal diode. Determine the output ripple voltage.

Figure1 (Circuit by PSPICE)

Figure2 (Output voltage in a buck-boost converter)

Figure3 (Output voltage ripple in a buck-boost converter)

The is AC voltage with 120V at 60 Hz. So . You can find this in figure3. And Vs is like sinusoidal because it is AC volatge. And I got a graph almost same with figure 5-22 in Mohan`s book. And can act like rectifier.
b) Briefly, express the principle of Single-phase rectifier.
In single-phase rectifier, a large filter capacitor is connected on the dc side. The utility supply is modeled as a sinusoidal voltage source in series with its internal inductance. To improve the line-current waveform, an inductor may be added in series on the ac side, which in effect will increase the value of inductor. The object is to throughly analyze the operation of this circuit. Although the circuit appears simple, the procedure to obtain the associated voltage and current waveforms in a closed form is quite tedious. In the top group, the cathodes of the two diodes are at a common potential.
