Design of universal H-bridge converter for cascaded multilevel topologies
Abstract
A new universal multi H-bridge converter is introduced in this paper. The main purpose of proposed universal converter is simple testing of modular multilevel topologies as CHB and M2LC topology. The whole converter is designed to fit a standard 2U height 19” rack mount enclosure. The converter consists of four 5 kW power cards with H-bridge IGBT modules. There are front and back panels in the converter construction dedicated to connecting a control unit, necessary quantities signaling, and enabling different and modular topology configurations using power terminals interconnection. The converter is also equipped with inevitable protections and measurements.
