Popis:	91 Two-inductor boost converter with auxiliary transformer is suitable for applications with a large difference between the input and output voltage. The converter is achieved in a wide load range with constant-frequency control by employing an auxiliary transformer that couples the current paths of the two boost inductors. Zero-Voltage-Transition techniques which combine PWM with the soft-switching characteristics make the converter can be operated at constant frequency. ZVT structure has no increase voltage and current stress. The rectifier diode also has soft-switching characteristic. Therefore, ZVT converters have the minimum conduction loss. This thesis will analyze and discuss the characteristics of the ZVT-PWM technique applied to the two-inductor boost converter.
