大变比输入串联输出并联链式DC-DC变换器

High-voltage and high-power dc-dc conversion is key to dc transmission, distribution, and generation, which requires compact and efficient dc transformers with large step ratios. This paper introduces a dc-dc converter with the input-series-output-parallel arrangement of multiple high step ratio subconverter units. Each subconverter unit is an isolated modular dc-dc converter with a stack of half-...
