converters are buck , boost and buck – boost circuits, which provide low/high voltage and current ratings for loads at constant switching frequency [1]. The topology of DC-DC converters consists of linear (resistor, inductor and capacitor) and nonlinear (diode and dynamic switch) parts. A buck converter , as shown in Fig. 1, is one of the most

https://newsmaidstone.blogspot.com/2022/01/boost-converter-design-example.htmlBuck Switching Converter Design Equations . The buck converter is a high efficiency step-down DC/DC switching converter . The converter uses a transistor switch, typically a MOSFET, to pulse width modulate the voltage into an inductor. Rectangular pulses of voltage into an inductor result in a triangular current waveform.
