Abstract

Three-level inverter topologies have been commonly used in high power applications, while a special protection control scheme is required, and many users tried to implement this with costly circuits externally. This application report discusses how to use minimum configurable logic block (CLB) resources to implement the protection logic for three phase three-level inverter.
