The buck–boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is equivalent to a flyback converter using a single inductor instead of a transformer. Two different topologies are called buck–boost converter. Both of … See more The basic principle of the inverting buck–boost converter is fairly simple (see figure 2): • while in the On-state, the input voltage source is directly connected to the inductor (L).
