GATE Electrical Engineering (EE) 2016 Shift 2 Solved Paper

A buck-boost DC-DC converter, shown in the figure below, is used to convert $24\mathit{V}$ battery voltage to $36\mathit{V}$ DC voltage to feed a load of $72\mathit{W}$. It is operated at $20\mathit{k}\mathit{H}\mathit{z}$ with an inductor of $2\mathit{m}\mathit{H}$ and output capacitor of $1000\mathit{\mu }\mathit{F}$. All devices are considered to be ideal. The peak voltage across the solid-state switch (S), in volt, is ____________.
