In this paper, by change of integration path in complex spectrum domain and by defining input admittance as the ratio of complex radiated power to amplitude of square of voltage across the gap, new expressions of admittance (valid for all frequencies) of infinitely long cylindrical antenna with and ...

This paper has proposed a fault detecting method for DC supplied permanent magnet synchronize motor (PMSM) drive systems by monitoring the drive DC input current. This method is based on the fault signal propagation from the torque disturbance on the motor shaft to the inverter input currents. The a...

Transient performance for output regulation problems of linear discrete-time systems with input saturation is addressed by using the composite nonlinear feedback (CNF) control technique. The regulator is designed to be an additive combination of a linear regulator part and a nonlinear feedback part....

Smart grid is the flag under which the US DoE has been mobilizing efforts to modernize the grid. Electronictization is the first step towards a smart modern grid. It is a process that transforms the grid from electrical and electromechanical (EE) to electronic, electrical and electromechanical (EEE)...

In view of the DC fault current isolation deficiency for the conventional half-bridge sub-module (HBSM) based modular multilevel converter (MMC), this paper presents an improved MMC topology. Both quasi reverse blocking submodules (QRBSMs) and current limit modules (CLMs) are employed to improve the...
