A Design And Development Of A Universal Power Supply For Laptops In Motor Vehicles

Abstract

This thesis deals with design of DC power supply with adjustable output voltage, workingin buck-boost topology. Thesis explains selection of buck-boost controller integradet circuit and calculationof values of external components. Designed converter is simulated in LTspice software,where parasitic properties of used components are included. There are summarized parameters ofconverter in different working states. Further there are mentioned planned expansions of converter,including microcontroler integration with user interface.
