For a buck and boost circuit, determine$/$draw:

The circuit of the power stage.

The operating principle by inspecting the components.

The expression for the output voltage $($derive it$).$

Given $V_{in}=10V_{}{f}_{sw}=20kHz,L=10mH,$ duty cycle $d=40\%,$ and load $R_{\text{l}\text{o}\text{a}\text{d}}=220,$ draw the waveforms of the static operation.

Analyze the circuits to determine the current direction and the voltage polarity on the load. Draw the waveforms and obtain the static voltage conversion function.
