两级式固态变压器子模块内部电流应力的可靠性导向路由

Power routing has emerged as a promising technique for balancing the remaining useful lifetime of modular converters, e.g., solid-state transformers (SSTs). However, this approach does not address the internal stress distribution within the individual two-stage submodules. In this article, a method to balance the internal stress by redistributing the second harmonic current between the dc-link cap...
