Classification of Converters

The converter topologies are classified as:

• • Buck Converter: In Figure 2a a buck converter is shown . The buck converter is step down converter and produces a lower average output voltage than the dc input voltage.

• Boost converter: In Figure 2b a boost converter is shown. The output voltage is always greater than the input voltage.

• Buck-Boost converter: In Figure 2c a buck-boost converter is shown. The output voltage can be either higher or lower than the input voltage.
