This paper proposes a competent and effective scheme to enhance the ride-through capability of DFIGbased wind turbines under unbalanced voltage dip conditions. The proposed method is realized through joint use of the rotor-side converter control and a three-phase stator damping resistor (SDR) placed in series with the stator windings. By means of an asymmetrical SDR idea, during the unbalanced ...

One of the most popular power management regulators is low drop-out voltage regulator (LDO). LDOs have different specifications such as supply rejection (PSR) over frequencies, stability load ranges, inrush current spike flows through input supply, and consumption. In this work, we present a LDO design with techniques for PSR improvement across frequencies. The presented in work low-power small...

Circuit Breaker is one of the most critical elements of power industry. Controlled Switching of grid voltage and grid current is the best solution to prevent the high inrush current and over voltages. This paper describes the Controlled Switching of Circuit Breaker by using multiprocessor based architecture. With this architecture early detection of most of major fault is feasible; it is also p...
