一种用于分布式光伏中压直流接口的低损耗串联LC功率平衡单元多端口模块化DC-DC变换器

An input-independent and output-series modular dc-dc converter with multiple input ports and high voltage conversion ratio can apply well to medium-voltage dc interface of distributed photovoltaics (PV). However, PV power mismatch will result in output voltage imbalance of the submodules (SMs), which is contrary to the standardized multimodule design. In this article, a multiport modular dc-dc con...
