The inductor here basically is used for stepping up the voltage and the capacitor is introduced for filtering the switching fluctuations and for reducing current ripples at the output of the converter. The inductor in a boost converter plays the important of stepping up the input voltage.
Efficient regulation ensures that the boost converter can maintain a constant output voltage despite variations or changes in the input voltage which contributes performance and its reliability. Hence this working mode makes the boost converter efficiency in stepping up voltage levels.
To successfully increase capacitor voltage beyond the driving voltage, we need to “pump” charge into the capacitor and prevent charge from flowing back into the source. The boost converter’s diode, which functions as a one-way valve for current, provides both of these actions:
Previously, we have seen another type of chopper circuit i.e., buck converter. Buck converters generate an output voltage that is lower than the supplied input. So, we can say, boost converters are the ones that perform a reverse operation of the buck converter.
A buck-boost converter provides an output voltage that can be either less than or greater than the dc input voltage V S. Hence the name “buck boost”. The output voltage polarity is opposite to that of the input voltage. It is a combination of buck and boost converters. Figure 1: Circuit Diagram of Buck Boost Converter.
All it has is an inductor, a semiconductor switch, a diode and a capacitor. The boost converter is very simple and requires very few components, this is because they were originally designed and developed in the 1960s to power electronics on aircraft. The biggest advantage of a boost converter is it offers very high efficiency.
