The Buck-Boost converter is able to provide a stable and highly efficient output voltage when the input voltage fluctuates greatly, thus providing a good balance between Buck-Boost converters are able to provide stable and efficient output voltages under large input voltage fluctuations, thus striking a good balance between high performance and miniaturized design. In this paper, we will discuss in detail the operation principle, application mode, efficiency characteristics and advantages of Buck-Boost converters in practical applications.

A Buck-Boost converter is a DC-DC converter capable of raising or lowering the input voltage to the desired output voltage, and its principle of operation combines the characteristics of buck (Buck) and boost (Boost) conversion. Unlike the traditional Buck and Boost converters, the Buck-Boost converter is able to ensure a stable voltage output even when the input voltage is higher or lower than the output voltage. Its main components include switches, diodes, inductors, output capacitors and control circuits. Specifically, the Buck-Boost converter converts the input electrical energy into the desired output electrical energy by adjusting the operating state of the switch.
In a Buck-Boost converter, the switches are usually switched at a high frequency so that the regulation of the electrical energy can be realized by controlling the duty cycle of the switching cycle.
