Design of stabilized dual power supply
Svoboda, Tomáš ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor’s thesis is focused on design and construction of stabilized dual power supply with adjustable output voltage in range 0 – 30 V and adjustable current limit in range 0 – 3 A. Power supply consists of line transformer, switching regulator and subsequent application of linear regulator for better output properties. Measurement of output voltage and current is realized by microcontroller ATmega644, which has optical separated inputs. In this thesis the device is designed and simulated. The design is verified by prototype device and then full construction is done. Construction is tested by measurements, which confirm a proper design.

Linear active filter of supply voltage „Ripple Blocker“
Vlček, Pavel ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This work deals with a methods for increasing the PSRR of the linear active filters of supply voltage or if linear regulators and voltage range of supply, primarily his minimal value. In the work are used ideal parts of reference voltage source and reference current source. The work describes how to eliminate effect of feedback loop on the PSRR, how to decrrease minimal power supply voltage and how to set stability of total schematic.
