一种减少元件数量的五电平开关电容单向整流器

This article proposes a three-phase five-level switched-capacitor unidirectional rectifier. The proposed unidirectional rectifier is derived from a bidirectional five-level active neutral point clamped topology by eliminating four active switches per phase. Even with fewer active switches, five voltage levels can still be synthesized at the input ac side, which leads to reduction of the size and w...
