Dual channel bench power supply
Stehlík, Ota ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
The aim of this thesis is to design and construct a two-channel bench power supply with variable output voltage in range from 0 V to 25 V with a maximum output current of 2 A. At the beginning of the thesis a general principles of power supplies are summarized. In the following section a detailed design description and simulation results of the main power supply are given. Afterwards, the design and description of auxiliary power supply with electronically controlled fan is presented. Finally, measured characteristics of the bench power supply are given.

Switched power supply with current limiting
Staněk, Michal ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
This thesis is focused on design and construction of switched mode power supply with continuous regulation of output voltage and current. The Power supply is designed as a switching power supply to reduce its weight and dimensions. To reach better parameters, it consists of two separate converters. The first one is isolated step-down controller with transformer. It supplies output the second controller (adjustable) and the measuring section with stable voltage. Input converter is designed as a simple single-transistor flyback converter. The TOPSwitch circuit was selected to reduce number of components. Output bench power supply is non-isolated buck converter with single transistor. For second converter the TL594 was selected as a control circuit, which typical aplication was modified to fulfill requirement of the bench power supply. Processor ATmega16 was used to show both required and actual values of current and voltage on a display.

General-purpose power supply with microcontroller
Jorda, Ivo ; Vyskočil, Pavel (referee) ; Brančík, Lubomír (advisor)
The aim of this thesis is design of adjustable switched mode power supply with symmetrical output of 25 V, and switched mode power supply with fixed output voltage of 5 V. Required maximum output current of each outputs is 3 A. At the beginning of the paper function of the basic SMPS topologies is described. Next all reqiured SMPSs are designed and chosen parts of the design are simulated. In the second half of the thesis assembly and testing of PCB are described as well as functions of programs. Last chapter contains results of meassurement of power supply paramters.
