基于PWM电流源变换器的风能转换系统

Current-source converters (CSCs) are a good candidate for the series-connected wind energy conversion system (WECS). However, the existing CSCs either exhibit poor generator stator current harmonics, require bulky low-frequency transformers, are limited in their application to synchronous generator-based wind systems, or necessitate complicated modulation and commutation. In this work, a new CSC i...
