Buck Boost Converter 4A about:
- 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 fly back converter using a single inductor instead of a transformer.
- Two different topologies are called buck–boost converter.
- Both of them can produce a range of output voltages, ranging from much larger (in absolute magnitude) than the input voltage, down to almost zero.
- When a buck (step-down) converter is combine with a boost (step-up) converter.
- The output voltage is typically of the same polarity of the input, and can be lower or higher than the input.
- Such a non-inverting buck-boost converter may use a single inductor which is use for both the buck inductor mode and the boost inductor mode, using switches instead of diodes.
- polarity of the output voltage is opposite to that of the input.
