Short description
The topology of the Buck-Boost converter is shown above which has the following electrical components:
- a DC input voltage
- a load resistor R,
- a filter capacitor C,
- an inductor L
- and two complementary switches.
Drawing these elements in LaTeX can be achieved using CircuiTikZ package, built using TikZ/PGF.
