| Popis: | 104 The thesis presents a technology that based on single-stage flyback converter with coupling inductance, switch-capacitor and diode-capacitor (DC) snubber. Using secondary side the transformer leakage inductance and secondary side DC snubber make to L-C series resonance for obtained the zero current switching and voltage clamped. Therefore this converter can increase at least five times voltage gains. Moreover, the total output power can increase and reduce ripple by using the interleaved converter method for four phase module. Also, this thesis presents the analysis of power semiconductor devices, components selection, transformer design and magnetic flux density calculation for the proposed converters. This can use material properties to achieve good performance, reduce PCB board size, save cost and achieve the best performance of converter. Finally, simulation and experimental results are employed to verify feasibility of the proposed converter under the different devices. |
