In order to improve the performance of DC-DC converter for photovoltaic power generation systems, a Boost converter topology that introduces diode and capacitor units is proposed, which can achieve high voltage gain; at the same time, the two inductors in the new topology are integrated by using the decoupling magnetic integration theory, which forms a new type of integrated inductors based on the EE core to reduce the size of the magnetic components. The feasibility of the topology and the new magnetic parts design proposed is verified by simulation analysis, and finally an experimental prototype is built to verify the effectiveness of the proposed high-performance DC-DC converter.
