Abstract: [cze] [eng]
Napln teto bakalarske prace, je popis ruznych topologi, pouzvanych pri konstrukci spnanych zdroju a nasledne vyuzit nabytych znalost k vyberu vhodne topologie, kon- strukci napajecho zdroje pomoc vybrane topologie a nasledne konstrukci laboratornho zdroje jakozto celku. Obsahem ideoveho navrhu tedy je napajeci cast zdroje zalozena na topologii pouzvane prave u spnanych zdroju, dale na regulatoru pracujcm jako snizujc menic rzeny PWM a rdc cast, jejimz hlavnim prvkem je 8-mi bitovy mikroprocesor. Pri navrhu je ukazana prace s navrhovym programem PXLS Expert a programem pro navrh plosnych spoju EAGLE. Simulace ukazane v teto praci jsou provadeny v programu OrCad PSPice. Cl prace spocva v oziven vsech funkcnch bloku jako jeden celek a nasledne nameren zakladnch parametru, ktere jsou zpracovany gracky. Vsechny namerene pa- rametry jsou v zaveru srovnany s parametry ocekavanymi a se simulacemi zskanymi pri ideovem navrhu. Zaverem prace je zhodnocen vsech zjistenych vysledku a porovnan s prvotnmi cli teto prace. The aim of this thesis is a description of the dierent topologies used in switching power supply and subsequent use of acquired knowledge to select an appropriate topology, power supply, using the selected topology and the subsequent construction of laboratory source as a whole. Ideological content of the proposal are part of the power source based on the topology being used in switching power supplies, also on the controller working as buck converter controlled by PWM and the control section, whose mainfeature is the 8-bit microprocessor. The design is shown working with the designprogram PXLS Expert and the program for PCB Design EAGLE. Simulation shown in this thesis are implemented in the program OrCAD PSPice. Objective is to ervive all the functional blocks as a whole and the subsequent measurement of basic parameters, which are pro- cessed graphically. All parameters are measured at the end compared with the expected parameters and the simulations generated in the ideological content. Finally, the work is to evaluate all of the results obtained and compared with the primary objective of this work.
