Popis
Shrnutí:With the development of sustainable energy industry, aerospace, power electronics technology, and electric vehicles, the demand for energy has become more urgent for humanity. A three port converter (TPC) that can combine photovoltaic cells with batteries has become a better solution at present. However, it is difficult to obtain an ideal TPC. Current TPCs typically have large weight, low efficiency and their topology has a lot of optimization space. This article proposes a topologies inference algorithm for TPC which describes the implementation process of various methods in detail. Different TPC topologies are obtained and experimentally verified. By comparing the different deduction methods proposed, a prototype was developed through branch combination multiplexing. The TPC uses gallium nitride (GaN) high electron mobility transistors (HEMTs) to operate at a frequency of 200 kHz. The power density of it reaches 5.291 W/cm3 and achieving a 92.8% efficiency with semi-regulated bus architecture.
