The complex fault computation is one of the important parts in power system calculation. This paper considers complex fault computation including short circuit and phase-broken fault at the same time. All parameters of power systems networks are stored in Microsoft Access. Complex fault computation using object oriented programming Visual Basic language has resulted in a greater accuracy and convenient...
A low-voltage discrete time forth-order Sigma-Delta modulator using input feed-forward is implemented. With careful signal scaling, signal swings inside the loop filter are suppressed to less than 50% of the reference voltage, which is highly desirable for low-voltage designs. The proposed single-loop single-bit input feed-forward topology is a simple and robust solution for low-voltage low-power...
