Non-Isolated converters.

Non-Isolated converters.

The majority of the topologies used in today’s converters are all derived from the following three non-isolated versions called the buck, the boost and the buck-boost. These are the simplest configurations possible, and have the lowest component count, requiring only one inductor, capacitor, transistor and diode to generate their single output. If isolation between the input and output is required, a transformer must be included before the converter.
