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.
