一种基于Cuk电路的紧凑型差分功率处理集成电路，具有集成磁性元件和软开关控制器，可实现电池级最大功率提取

In this article, a cell-level differential power processing integrated circuit (IC) is presented to perform maximum power point tracking on photovoltaic cells under mismatch conditions, such as partial shading. To reduce the form-factor of the design, a bidirectional Cuk-based converter is implemented by integrating magnetics on the packaging bond wires. Using variable frequency TCM, a novel close...
