用于三电平ANPC变换器的正弦频率分布双倍频三角电流模式调制

Triangular current mode (TCM) modulation is a well-researched technique for optimizing the trade-off between converter power or gravimetric density and power efficiency. However, its application in multilevel ac–dc converters has been limited. This article extends the TCM concept to a three-level active-neutral-point-clamped converter and addresses key implementation challenges. First, two fundame...
