Converter for supplying of the power LED diode
Puczok, Václav ; Huták, Petr (referee) ; Patočka, Miroslav (advisor)
The aim of this thesis is to design a grid-powered supply for supplying power LED used in illuminating application. The power supply consists of an input line filter which attenuates conducted high frequency signals (EMI filter), an active rectifier (PFC circuit) to improve the power factor and the main constant output current double-sided forward converter. It thoroughly focuses at design of the converter's power stage, mainly at pulse transformer, switching transistors, output rectifier and output filter. Main converter model was created in the Matlab-Simulink environment in order to simulate behaviour of the current loop. Final product of this work is a fully functional power supply and the main converter's model.
