无中点H型三电平逆变器

This article introduces a neutral-point-less H-type (NPL.H) 3-level dual inverter topology for motor drive applications. This multilevel topology craftily eliminates the neutral clamp and neutral point current altogether, resulting in a drastically lower minimum dc-link capacitance, compared with conventional 3-level inverter topologies, while retaining the multilevel benefits. NPL.H has additiona...
