Research on High Performance DC/DC Converter Designed for BIPV

Building Integrated Photovoltaic (BIPV) system is an innovative way of integrating photovoltaic power generation technology into architectural design. In view of the requirements of high gain, small size and high power density of the internal DC-DC converter of BIPV system, this paper proposes a new boost circuit design scheme by inserting a C-D-D-C unit into the traditional boost topology to improve the gain; and a new magnet design method by using decoupling integration technology to integrate two inductors in the boost circuit together, which effectively reduces the size and weight of the magnet and improves the system power density. At the same time, a new magnet design method is proposed to integrate the two inductors in the boost circuit by decoupling integration technology, which effectively reduces the size and weight of the magnet and improves the power density of the system, and finally, the feasibility and accuracy of the high-performance DC-DC converter scheme proposed in this paper are verified by simulation and experiment.
