Design of double stabilized power supply
Vlček, Pavel ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This work deals with a design scheme of a laboratory power supply with high stability of output voltage and additional protections for safer operation of both powered device and the power supply itself. The work describes complex construction of power supply from the design of scheme in the simulator, through its tuning to the required parameters and the design of mains transformer to the construction and building of resulting device applicable in a laboratory. In addition, measuring and evaluation of achieved parameters, such as the ripple of the output voltage, the velocity of reaction current limitation, velocity of reaction the thermal electronic fuse are given.

Power supply
Matějů, Jan ; Uher, Miroslav (referee) ; Beneš, Petr (advisor)
This work is focused on development of a laboratory power source with low output ripple, its construction and measuring its basic parameters. Basic point of interestion is systems design of a digital controled power source. Document describes problems which has occured and its solutions. Describes designing of a circuit board, its construction and measuring its parameters. Below describes system design, construction and examination of a display and keyboard for operating the device. As a result of this work is realized and measured system design, which achieved relativem low levels of output ripple, short reaction time on change of load, but slower reaction of a current limit. Some parameters has not been entirely fine-tuned, especialy speed of reaction of current limit, amplitude of output distortion volage and stability diring short circuit on output clamps.
