The SRC is constructed using LLC resonant tank which is driven by a half-bridge circuit with fixed 50%-duty carrier frequency. The resonant phenomenon can be obtained by using of the leakage inductance of primary coil, the magnetizing inductance of the transformer, the resonant capacitor and parasitic component of power MOSFETs. Moreover, the zero-voltage-switching (ZVS) can be achieved using resonant phenomenon to reduce the switching loss. Furthermore, the synchronous rectifier is added in the secondary side of transformer by using the power MOSFETs in place of the diode to reduce the conduction loss. In addition, to improve the transient response of the voltage regulation during load variation, two intelligent controls are proposed. One is the probabilistic fuzzy neural network (PFNN), and the other is the TSK-type probabilistic fuzzy neural network with asymmetric membership function (TSKPFNN-AMF). The network structures, online learning algorithms and convergence analyses of the PFNN and the TSKPFNN-AMF controls are introduced in detail. Finally, the feasibility of the proposed control schemes are verified through experimentation. Faa-Jeng Lin Muh-Tian Shiue 林法正 薛木添 2013 學位論文 ; thesis 121 zh-TW |
