A buck-boost half-bridge converter is a type of power electronic circuit used for AC-DC conversion and DC-DC voltage regulation. It combines elements of both buck and boost converters along with a half-bridge topology to achieve its functionality. Let's break down the concept and its use in AC-DC conversion:
Buck Converter: A buck converter is a DC-DC converter that steps down (reduces) the input voltage to produce a lower output voltage. It uses a switching transistor (typically a MOSFET) and an inductor. When the transistor is switched on, current flows through the inductor, storing energy in its magnetic field. When the transistor is switched off, the inductor releases this stored energy to the load. By controlling the switching frequency and duty cycle of the transistor, the output voltage
