轻载下模块化多电平变换器故障定位的潜在失效风险及基于电流重塑的解决方案

In the state-of-the-art fault location of modular multilevel converters, capacitor voltage deviations between the faulty and healthy submodules are extensively utilized to identify open-circuit faults. However, there is a potential risk of overlooking the ineffectiveness of the fault location under light load conditions. This article presents an analytical model that reveals the fault phenomena an...
