SYNCHRENOUS RECTIFIERS IN SWITCHMODE POWER SUPLIES
Špatenka, Jan ; Sedláček, Jiří (referee) ; Murina, Milan (advisor)
The aim of this project is synchronous rectifier in switched-mode power supply. The project deal with possibility, how increase in efficiency in SMPS. For increases in efficiency are very important analysis particular power losses. One from possibility how increase in efficiency is replace Schottky diode in output rectifier by synchronous rectifier, with is consists of a power MOSFET. The second part of this work is focused on practical realization SMPS with synchronous rectifier and with output power . The main task was reach high efficiency. On the end of there is comparing of rectifiers and electric measuring has been making.
