5 Summary

This application report introduces an upgraded design to achieved delayed protection for three phase inverter with minimum of CLB resources. Meanwhile, this can simplify the software design with less software overhead during the zero crossing point in every AC cycle. The design is also validated and adopted in actual applications.
