In this thesis, a novel high step-up DC-DC converter is proposed and realized. This converter combines a Zeta converter with coupled-inductor technique and voltage multiplier to achieve high step-up voltage gain with maximum power tracking technology. The leakage inductance energy can be recycled, and thus the voltage stress and power loss can be reduced. In addition, the low voltage-rating switch with low conduction resistance can be used to improve the system efficiency. Since the maximum power point on each PV module can be controlled by individual power converter, the shading effect problem can be avoided. Then, the energy harvesting capability can be improved. Finally, converters with 20~ 40 V input voltage range and the maximum output 400 V/300 W is implemented in the laboratory to verify the performance of the proposed converter.
