What Is a DC-DC Converter and How Does It Work?

WebJun 21, 2024 · The components typically employed for this purpose include switches along with passive components like inductors, capacitors, and transformers. The use of resistors is avoided in order to reduce possible power losses. The way these components are interconnected depends on the desired method of power translation. Buck converters typically contain at least two semiconductors (a diode and a transistor, although modern buck converters frequently replace the diode with a second transistor used for synchronous rectification) and at least one energy storage element (a capacitor, inductor, or the two in combination).
