Switching Regulators by Watlt Kester, Brian Erisman
This paper will detail the operating principles of the four most commonly used switching converter types:
Buck: used the reduce a DC voltage to a lower DC voltage.
Boost: provides an output voltage that is higher than the input.
Buck-Boost (invert): an output voltage is generated opposite in polarity to the input.
Flyback: an output voltage that is less than or greater than the input can be generated, as well as multiple outputs. Also, some multiple-transistor converter topologies will be presented:
Push-Pull: A two-transistor converter that is especially efficient at low input voltages.
Half-Bridge: A two-transistor converter used in many off-line applications.
Full-Bridge: A four-transistor converter (usually used in off-line designs) that can generate the highest output power of all the types listed. Application information will be provided along with circuit examples that illustrate some applications of Buck, Boost, and Flyback regulators
