Fast Detection of Open- Switch Fault in Cascaded H-Bridge Multilevel Converter

Abstract

Fell H-Bridge converter has as of late been used in various high-control applications because of its particular furthermore, basic structure. So as to have an adjusted many an issue event in this converter, it is important to recognize the switch issue and its area. In this paper, a quick power switch shortcoming discovery strategy is introduced to recognize the flaw and its area. One and only voltage estimation per stage is required by this technique, and the shortcoming identification is speedier contrasted with the existing techniques. In addition, it is simple for execution on an FPGA gadget, because of the utilization of basic math, social and state machine pieces. The proposed technique is confirmed by PC recreation.
