一种新型三相双输出中点钳位三电平逆变器

A novel topology of a three-phase dual-output neutral-point-clamped three-level inverter (DO-NPC-TLI) is proposed. DO-NPC-TLI can achieve two groups of ac voltage outputs with adjustable frequency and amplitude. We describe the topology in detail. The proposed topology is based on a neutral-point-clamped three-level inverter (NPC-TLI). A total of eight switches and six clamping diodes are added to...
